Page 15: Chapter 1 Introduction
Introduction What is the ProMark2 Survey System? ProMark2 is a complete GPS system providing both navigation and precision surveying. The ProMark2 system, Figure 1.1, includes two or more ProMark2 GPS receivers, GPS antennas, and all ancillary components required to get you up and running and producing quality survey data in a minimum amount of time.
Page 16: Items Supplied With Promark2
The ProMark2 System operates in conjunction with Ashtech Solutions, Thales Navigation’s highly-automated GPS post-processing engine. Ashtech Solutions is a complete, easy-to-use software package which manages and processes raw GPS data, deriving precise positioning data and presenting the results in easily understood report formats.
Page 17: External Gps Antenna
External GPS Antenna The external GPS antenna, Figure 1.3, is required for surveying functions. While the built-in antenna is sufficient for navigation, a more sophisticated external antenna is required to obtain quality data for precision surveying. The external GPS antenna is the physical data collection point for the raw GPS satellite data.
Page 18: Vertical Antenna Extension
Vertical Antenna Extension The vertical antenna extension, Figure 1.5, provides clearance for the antenna cable when the antenna is mounted on a tripod. The length is 3 inches (0.0762 m). Figure 1.5 Vertical Antenna Extension Field Receiver Bracket The field receiver bracket, Figure 1.6, serves a number of functions. First, it provides the means for mounting the ProMark2 GPS receiver to the tripod.
Page 19: Hi (Height Of Instrument) Measurement Tape
HI (Height of Instrument) Measurement Tape The HI measurement tape, Figure 1.7, is used to measure height of the GPS antenna over the survey point. The end of the tape hooks onto the antenna. The tape is extended until the spike on the tape case is on the point.
Page 20: Office Receiver Bracket With Download Cable
Office Receiver Bracket with Download Cable The office receiver bracket with integrated download cable, Figure 1.9, is an interface device that connects the ProMark2 receiver to an office computer for downloading of stored GPS satellite data. When the ProMark2 is placed into the bracket, the download cable is automatically connected to the receiver via the contacts on the back of the receiver.
Page 21: Documentation
The Ashtech Solutions post-processing software, Figure 1.11, provides the tools required to download and process the GPS satellite data from each ProMark2 receiver to produce relative positions of all points surveyed. Ashtech Solutions is provided on a CD which also contains a user’s guide.
Page 22: Additional Items Required But Not Supplied
Additional Items Required but not Supplied In order to conduct your survey, you will need some of the additional equipment discussed below. This equipment is not supplied with the standard ProMark2 survey system. Tripod, Tribrach, and Tribrach Adapter For each ProMark2 receiver in your system, you will need a tripod, tribrach, and tribrach adapter, Figure 1.12, Figure 1.13, and Figure 1.14, to position the GPS antenna over the survey point.

Page 24: Fixed-Height Gps Tripod
Fixed-Height GPS Tripod An option to the tripod, tribrach, and tribrach adapter combination is the fixed-height GPS tripod, Figure 1.15. The fixed-height GPS tripod has the advantage of eliminating the possibility of measuring and/or recording an incorrect HI, since the height is fixed. HI blunders are one of the most common mistakes during data collection.

Page 28: Surveying With Promark2
Surveying with ProMark2 The ProMark2 system is designed to perform GPS surveys using static, stop-and-go, and kinematic modes of GPS data collection. The three modes run independently and the GPS receiver must be turned off to run in a different mode. In the static data collection mode, the GPS receiver systems simultaneously collect raw data from all available satellites while remaining stationary on their respective points.
Page 29: Navigating With Promark2
In the kinematic data collection mode, the GPS receiver systems simultaneously collect raw data from all available satellites while a receiver is moving. In most cases, one GPS receiver system is located on a known point serving as a base station collecting data at that location for the duration of the survey.

Page 37: Chapter 2 Getting Started
Getting Started Overview This chapter discusses the basic features and operation of ProMark2. This is followed by a quick tour of the survey interface to show how ProMark2 can be used to collect survey data with accompanying point attribute data. Control Buttons Figure 2.1 shows the control buttons used for survey functions.
Page 38: Table 2.1 Control Buttons Used For Survey Functions
Table 2.1 Control Buttons used for Survey Functions Button ENTER The ENTER button is used to either execute the highlighted function, edit the highlighted parameter, or enter the highlighted value. To illustrate, refer to Figure 4.5 on page 110, which shows the Survey Menu screen. The Point Attribute function has been highlighted by using the up/down arrows.
Page 39: Battery Life
Battery Life The ProMark2 receiver is conveniently powered by 2 standard AA batteries. Any battery type in the AA form factor can be used in the ProMark2 receiver, including both disposables (alkaline, lithium) and Rayovac® IC3 rechargeables. Other rechargeables are not recommended.
Page 40: Figure 2.3 Low Battery Alarm
As is evident from the graph of the alkaline batteries, temperature plays a large part in the operational life. This is true for all battery types with the exception of lithiums. The lithium experiences little effect on operational life due to temperature, making lithium the best choice for low-temperature operation.
Page 41: Figure 2.4 Extreme Low Power Alarm
The final battery alarm is the Extreme Low Power alarm, Figure 2.4. When this alarm appears, the active survey data file is closed and the receiver is shut down after 10 seconds. The current batteries will need to be replaced in order to continue with the survey Figure 2.4 Extreme Low Power Alarm Getting Started...

Delete data from receiver after processing. Keep the data files in the receiver until after you have completed the processing. If a data file were corrupted during download, this procedure will provide you with the opportunity to download the file once again. Beware of large detailed street-level map files.
Page 44: Downloading Collected Data To Office Computer
Downloading Collected Data to Office Computer After you have collected data in the field, you must download the data to an office computer and process the data using the Ashtech Solutions software. Use the following procedure to download the receiver data. Insert the ProMark2 receiver into the office bracket, Figure 2.6, making sure that the ProMark2 is securely retained by the hook on the bracket.
Page 45: Chapter 3 Surveying With The Promark2 System
Surveying with the ProMark2 System This chapter presents step-by-step procedures for performing a GPS survey with the ProMark2 system. Review this chapter thoroughly before attempting to perform your first survey. As an exercise, take your system outside of your office and perform a sample survey following the procedures outlined below.
Page 46: Figure 3.1 Three-Point Control Survey Example
Figure 3.1 Three-point Control Survey Example If you were to perform this survey with a conventional total station, you would probably plan on running a closed-loop traverse from the existing control point through the two new points, Figure 3.2. The same philosophy can be used for GPS surveys. Figure 3.2 is your network design for this survey.
Page 47: Figure 3.3 15-Point Control Survey Example
horizontal and 3 existing vertical control points. Figure 3.3 15-Point Control Survey Example Again, if you were to perform this survey with a conventional total station, you would design a traverse plan which produced a strong looking network of closed-loop traverses through the points of the survey.
Page 48: Observation Plan
Although the network design in Figure 3.4 was produced with conventional traversing in mind, this same design can also be used if performing the survey with GPS equipment. When designing your network, keep the following principles in mind: • Design loops through the network points which resemble a square or circle. Avoid loops that are long and skinny.
Page 49: Figure 3.6 Network Design For 3-Point Control Survey
our 3-point control survey network design, shown again in Figure 3.6. Figure 3.6 Network Design for 3-Point Control Survey Assume that a 2-receiver ProMark2 system will be used to perform the survey in Figure 3.6. To produce the link between the existing control point 1 and the new point 2, simply place one ProMark2 receiver system on point 1, place the other receiver on point 2 and simultaneously collect data between the two points.
Page 50: Figure 3.7 Network Design For 15-Point Control Survey
Figure 3.7 Network Design for 15-Point Control Survey To execute this network design, you must perform a direct GPS observation between all points directly linked. Each link can be viewed as a required GPS vector. Counting the links in this network design, you will find that 19 GPS vectors are required to execute this design.
Page 51: Figure 3.8 Receiver Observation Plan For 15-Point Control Survey
Figure 3.8 Receiver Observation Plan for 15-Point Control Survey The observation plan shows that it will take 10 separate observation sessions to complete the survey based on the network design in Figure 3.7. Notice that all observation sessions, except for session 6, produce 2 vectors required from the network design. Observation 6 produces only one since there were an odd number of required vectors (19).
Page 52 location for the given time. Pay particular attention to satellite availability (number of satellites in view) and the satellite distribution. To assist in analyzing the quality of satellite distribution, Dilution of Precision (DOP) values are presented. DOP is a quality analysis value for satellite distribution.
Page 53: Performing A Static Survey With The Promark2
Performing a Static Survey with the ProMark2 The procedures for performing a static survey with the ProMark2 system can be broken down into four primary categories: equipment check , site selection , system setup , and data collection . Following the steps presented below should result in successful execution of your GPS survey.
Page 54 signals transmitted by satellites approximately 21,000 km from earth. Being of relatively high frequency and low power, these signals are not very effective at penetrating through objects that may obstruct the line-of-sight between the satellites and the GPS receiver. Virtually any object that lies in the path between the GPS receiver and the satellites will be detrimental to the operation of the system.
Page 55: System Setup
System Setup Now that the survey site is identified, it is time to set up the ProMark2 receiver system over the point to be surveyed. The setup procedure is illustrated below. Set up tripod / tribrach combination over the survey point. This is done in precisely the same manner as for a conventional total station.

Page 72: Kinematic Surveying With The Promark2 System
Kinematic Surveying with the ProMark2 System The kinematic data collection process requires at least two receivers collecting data simultaneously. One receiver is called the base and must remain stationary throughout the data collection. Typically, the base receiver will occupy a survey point for which the precise position is already known.
Page 73: Stop-And-Go Or Kinematic Base
after a loss of lock is critical to maintaining survey accuracy. Finally, kinematic surveys are most successful when the kinematic base receiver is close to the kinematic rover. Accuracies of GPS-derived positions are distance-dependent. The greater the distance between the GPS receivers, the larger the uncertainty. In an ideal case, the kinematic base should be on the same project site as the kinematic rover.

initialization, be sure to incorporate the bar as part of your base setup as shown in Figure 3.26. Figure 3.26 ProMark2 Antennae with Initializer Bar Note: The base antenna is centered and levelled above the survey mark. The rover antenna is offset on the initializer bar.
Page 75: Kinematic Initialization
The rover antenna is transferred to the rover pole after initialization is completed, Figure 3.28. Figure 3.28 Rover Antenna from Initializer Bar to Range Pole Kinematic Initialization Overview A unique aspect of the kinematic mode of data collection is the requirement to initialize the survey.
Page 76: Bar Point Initialization
described below along with recommendations on when to use them. Bar Point Initialization Bar Point initialization is specific to ProMark2 and is performed using the supplied kinematic initializer bar. Bar Point initialization is the second quickest method of initializing a kinematic survey after initializing on a known point.
Page 77: Known Point Initialization
Known Point Initialization The quickest method to initialize a kinematic survey is Known Point initialization. In most situations, initialization on a known point can be accomplished in 10 seconds or less. It's very important to note that the relationship between the kinematic base point and the known point to be used to initialize must be very accurately established.
Page 78 point 0017, you get too close to the building causing the Kinematic SV Alarm to sound, indicating loss of initialization. You must re-initialize. You return to the initializer bar. If you were careful not to move (rotate) the bar, you can treat the bar point as a known point and perform a Known Point initialization.
Page 79: New Point Initialization
New Point Initialization The New Point method of kinematic initialization is the most time consuming method. It should be used only when other methods are not feasible. Observation times for initialization using the New Point method range from 15-30 minutes for a ProMark2 System. The observation time depends on the distance between the kinematic base and kinematic rover during initialization.
