GNSS antenna The GNSS receiver is connected to the IMU with an RS-232, RS-422 or SPI link. A NovAtel GNSS antenna must also be connected to the receiver to track GNSS signals. After the IMU enclosure, GNSS antenna and appropriate power supplies are attached, and a few simple configuration com- mands are entered, the SPAN system will be ready to navigate.
Use raw phase observation data (to constrain INS solution drift even when too few satellites are available for a full GNSS solution) For more information about GNSS and INS, refer to www.novatel.com/an-introduction- to-gnss/ 1.2 Models and Features All SPAN system receivers are factory configurable for L1/L2 RTK capability and are compatible with an IMU.
This manual contains sufficient information about the installation and operation of the SPAN sys- tem. It is beyond the scope of this manual to provide details on service or repair. Contact your local NovAtel dealer for any customer service related inquiries, see Customer Support on page 21.
Chapter 2 SPAN Installation Chapter 2 SPAN Installation A SPAN system consists of an OEM7 receiver, an IMU, a GNSS antenna, power and a com- munication link (if your application requires real time differential operation).

Chapter 3 SPAN Operation Figure 24: Local-Level Frame (ENU) 3.1.2 The IMU Body Frame The definition of the IMU Body frame is given by the physical axes of the IMU and represents how the sensors are mounted inside the IMU. If your IMU is enclosed, both the IMU Body frame axes and center of navigation are marked on the enclosure.
Chapter 3 SPAN Operation Figure 26: Vehicle Frame 3.1.4 The User Output Frame The user output frame is an arbitrary frame, which can be optionally defined to transfer inertial output to a more useful position or reference frame. By default, SPAN position and velocity output is given at the center of navigation of the IMU. To output position and velocity at a different location, specify a user offset translation using the SETINSTRANSLATION command.
Page 74
Chapter 3 SPAN Operation The translational offsets are measured in three directions, X axis, Y axis and Z axis, typically rel- ative to the IMU Body frame. Translational offsets can also be entered relative to the Vehicle frame. The X, Y and Z axes of the IMU Body frame are typically indicated on the IMU enclosure. The X, Y and Z axes of the IMU Body frame are also indicated on the mechanical draw- ings of the IMUs in the IMU Technical Specifications on page 114.
Chapter 3 SPAN Operation The translational offsets from the IMU to the GNSS antenna are required for all SPAN systems. However, some SPAN systems may have other sensors or devices integrated into the system for which the SPAN needs translational offsets. For example, a gimbal mount or a camera or LiDAR connected to an Event Input line.
Page 76
Chapter 3 SPAN Operation To reach this answer, keep in mind the following rules: The goal is to rotate the IMU Body frame to be coincident with the Vehicle frame (i.e. IMU X equals Vehicle X, IMU Y equals Vehicle Y, IMU Z equals Vehicle Z). You must rotate from the IMU Body frame to the Vehicle frame.
Chapter 3 SPAN Operation The rotational offsets are entered using the SETINSROTATION command. For this example, the command to enter the rotations for the previous example is: SETINSROTATION RBV -90 0 90 3.3 Software Configuration On a SPAN system, both the GNSS receiver and the IMU must be configured. 3.3.1 Minimum Recommended Configuration When configuring your OEM7 SPAN system for first time use, the following is the minimum amount of information required to ensure proper operation of a SPAN system.
Use the COM port number the IMU is connected to. If you are using the OEM719+MIC board stack, you must use COM1. For SPAN systems with a OEM729 receiver, COM2 is the recommended serial port for the IMU, however you can use any available port for these IMUs When the ADIS16488 is connected using a MIC.
Page 80
Use the COM port number the IMU is connected to. If you are using the OEM719+MIC board stack, you must use COM1. For SPAN systems with a OEM729 receiver, COM2 is the recommended serial port for the IMU, however you can use any available port for these IMUs When the STIM300 is connected using a MIC.
Page 81
Chapter 3 SPAN Operation This example shows a mounting configuration with a negative X offset, negative Y offset and positive Z offset. A typical RTK GNSS solution is accurate to a few centimetres. For the integrated GNSS+INS system to have this level of accuracy, the offset must be measured to within a centimetre. Any offset error between the two systems shows up directly in the output position.
Routine on page 91. SPAN Configuration with NovAtel Connect NovAtel Connect provides a wizard that takes you through the steps required to configure a SPAN system. For information about using the SPAN Configuration wizard in NovAtel Connect, refer to the help file available within NovAtel Connect.
Chapter 3 SPAN Operation available from the SPAN system through the GNSS-specific logs, even without SPAN running. The integrated GNSS+INS solution is available through special INS logs documented in the OEM7 Commands and Logs Reference Manual. The IMU raw data is available at the maximum rate of output of the IMU. Because of this high data rate, a shorter header format was created.
Chapter 3 SPAN Operation Binary ASCII Description The INS filter has determined the IMU orientation, received an initial WAITING_ position and completed initial bias estimates. Azimuth input (from AZIMUTH vehicle motion, dual antenna or command) is required for alignment. INITIALIZING_ The INS filter has determined the IMU orientation, received an initial BIASES position and is conducting an initial IMU bias estimate.
Page 85
Chapter 3 SPAN Operation pitch and heading are computed. Because the coarse alignment uses averaged sensor output, the vehicle must remain stationary for the duration of the alignment, which is approximately 45 seconds. The attitude estimates solved by the alignment are larger than the system specified attitude accuracy and vary upon the characteristics of the sensor and the geographic latitude of the system.
Chapter 3 SPAN Operation Dual Antenna Alignment SPAN can also use heading information available from a NovAtel Dual Antenna ALIGN solution to rapidly perform an alignment. Refer to SPAN with Dual Antenna on page 108 for details. NVM Seeded Alignment SPAN can use the alignment information from a previous power up to quickly perform an align- ment.

IMU is attached), GNSS logs can be requested at rates up to 20 Hz. Ensure that all windows, other than the Console, are closed in NovAtel Connect and then use the SAVECONFIG command to save settings in NVM. Otherwise, unnecessary data logging occurs and may overload your system.
Specific logs need to be collected for post-processing. See Data Collection for Post Processing on page 100. To store data from an OEM7 receiver, connect the receiver to a computer running NovAtel Con- nect or other terminal program capable of recording data. On PwrPak7 receivers, you can also collect data on internal memory.
Chapter 3 SPAN Operation The steps involved in the calibration are: 1. Apply power to the receiver and the IMU. 2. Configure the SPAN system, see SPAN Configuration on page 79. 3. Perform an initial system alignment using one of the methods described in System Start-Up and Alignment Techniques on page 84.
Chapter 3 SPAN Operation 5. Enable calibration using the INSCALIBRATE command with an optional standard deviation target. INSCALIBRATE RBV NEW [target_stdev] 6. To monitor the calibration, log INSCALSTATUS using the ONCHANGED trigger. 7. Start to move the system. As with the lever arm calibration, movement of the system is required for the observation of the angular offsets.
Page 93
Chapter 3 SPAN Operation Figure 28: Multi-Line IMU Body to Vehicle Calibration The steps for the calibration routine are: 1. Apply power to the receiver and IMU. 2. Configure the SPAN system, see SPAN Configuration on page 79. 3. Ensure that an accurate lever arm has been entered into the system either manually or through a lever arm calibration, see Lever Arm Calibration Routine on page 90.
Chapter 3 SPAN Operation 9. Initiate the second pass of the calibration by issuing the INSCALIBRATE command with the ADD parameter: INSCALIBRATE RBV ADD 10. Drive the vehicle back along the original course, until you reach the starting point for the first pass.
Chapter 3 SPAN Operation Time Guard (t_guard): The time guard specifies the minimum number of milliseconds between pulses. This is used to coarsely filter the input pulses. The time of the input pulses is available from the MARKTIME, MARK2TIME, MARK3TIME and MARK4TIME log.
Chapter 3 SPAN Operation Valid Event Outputs Valid Event Inputs MARK3 MARK3 MARK4 MARK4 3.6.2 Configuring the Software Sensor objects are defined by using the SETUPSENSOR command. This command allows the Event_In and Event_Out lines to be specified as well as some parameters for the outgoing and incoming signals.
Chapter 3 SPAN Operation For the PwrPak7, the wheel sensor is connected to the HD26 COM PORTS connector For the IMU Enclosure (IMU-HG1900, IMU-ISA-100C, IMU-ENC-LN200 or IMU-µIMU-IC), the wheel sensor is connected to the Wheel Sensor port using the optional Wheel Sensor Cable (60723137) or a custom cable.
Chapter 3 SPAN Operation 3.7.2 Wheel Sensor Data Collected on IMU The SPAN system uses the wheel sensor data passed in and timed through the IMU-CPT, IMU- FSAS, IMU-IGM, IMU-HG1900, IMU-ISA-100C, IMU-ENC-LN200 or IMU-µIMU-IC. This timed data is passed to the GNSS+INS filter to perform the update. The timed data is also available through the TIMEDWHEELDATA log.

After that is provided, the system will automatically compute the variable lever arm and produce several messages for output.
Chapter 3 SPAN Operation Table 22: Logs used with Variable Lever Arm Description This log displays the calculated variable lever arm. VARIABLELEVERARM The VARIABLELEVERARM log is output in IMU Body frame. This log has the same format as the INSPVA log, but contains the attitude rotated back to the null gimbal position.
Explorer for post-processing. 3.12 Relative INS NovAtel's Relative INS technology generates a position, velocity and full attitude vector between two SPAN systems. One is the Master receiver and the other is the Rover receiver. Once con- figured, the Master receiver begins transmitting corrections to the Rover receiver. Relative information is created and the system begins filling the RELINSPVA log and SYNCRELINSPVA log on the Rover receiver.
Chapter 3 SPAN Operation Figure 31: Relative INS Example An important command that can be used with Relative INS to manually change the maximum amount of time to use RTK data is the RTKTIMEOUT command. This command is used to set the maximum age of RTK data to use when operating as a rover station.
Page 107
Chapter 3 SPAN Operation To configure Relative INS using the RELINSAUTOMATION command, the mater and rover receivers must be communicating using a COM port. If the master and rover are communicating via an ICOM port, the RELINSCONFIG command must be used. The Model option must be present on both the rover and master for the Relative INS fea- ture to be enabled.
For information about connecting the ALIGN master and rover receivers using a port that is not a serial COM port (e.g. Ethernet), contact NovAtel Customer Support. OEM7 SPAN Installation and Operation User Manual v4...

Chapter 4 SPAN with Dual Antenna The two receivers need to be set up as shown in the example in Figure 32: SPAN - Two Receiver Dual Antenna Installation below. Dual antenna receivers, such as the OEM7720, contain the hardware necessary to provide an ALIGN solution without an additional receiver.
Chapter 4 SPAN with Dual Antenna Figure 33: SPAN - Single Receiver Dual Antenna Installation 4.2 Configuring ALIGN with SPAN Before configuring the ALIGN solution, the two receivers should both be powered on and con- nected directly between COM 2 of the SPAN receiver and COM 2 of the second receiver through either a null modem cable or an appropriate radio connection.
Chapter 4 SPAN with Dual Antenna The rover receiver must be an ALIGN-capable model. To enable the dual-antenna ALIGN solution to aid the INS alignment and provide heading updates, the offset between the antennas and the IMU must be known. This is achieved by enter- ing lever arms to both antennas, using the SETINSTRANSLATION command.
Chapter 4 SPAN with Dual Antenna For optimal SPAN performance when using Dual Antenna with SPAN an ALIGN offset cal- ibration is required for each unique installation. This calibration refines the IMU to antenna baseline angular offset from the initial estimate derived from the input lever arms.
Chapter 4 SPAN with Dual Antenna The first available technique will be used, regardless of its relative quality. If you wish to guar- antee a specific technique is used, or use an aided static alignment, you must select the desired alignment mode manually.

APPENDIX F Frequently Asked Questions 1. How do I know if my IMU is connected properly? a. Refer to the VERSION log. If your IMU is communicating with a SPAN enabled receiver, the IMU details will be included in the log. b.
Page 286
APPENDIX F Frequently Asked Questions b. If the INSCOMMAND command has been set to START_FINE_TIME, the RAWIMU logs are not available until the system has solved for time. This requires that an antenna is attached and satellites are visible to the system. You can verify that time is solved by checking the time status in the header of any standard header SPAN log such as BESTPOS.

APPENDIX F Importance of Antenna Selection APPENDIX F Importance of Antenna Selection An antenna behaves both as a spatial and frequency filter, therefore, selecting the right GNSS antenna is critical for optimizing performance. An antenna must match the receiver’s cap- abilities and specifications, as well as meet size, weight, environmental and mechanical spe- cifications for the intended application.
Page 288
APPENDIX F Importance of Antenna Selection Figure 134: Plot of Good and Poor Antenna Phase Center Variation over Elevation Angle 0-90° Many users can accept accuracies of less than a metre so these small phase center vari- ations cause a negligible amount of position error. But if you require high precision, Real Time Kinematic (RTK) receivers can achieve position accuracies of 2-4 cm and a few mil- limetres of phase center error translates to a 10-15% error in reported position.
Page 289
APPENDIX F Importance of Antenna Selection temperatures and vibration profiles. Survey rover antennas should be able to survive rough handling by surveyors including a pole drop. The table below highlights some of the important desirable features needed for a GNSS antenna based upon the user’s application.
