    Hardware Integration General Description NAVIOR-24S provides asynchronous serial port. NAVIOR-24S module is designed as a DCE (Data Communication Equipment), following the traditional DCE-DTE (Data Terminal Equipment) connection, the module and the client (DTE) are connected through the following signal (as Figure II-1 shows).

  • Page 33: Connectors

    Hardware Integration Connectors Digital IO/Power Connector The NAVIOR-24S GPS/GLONASS module uses a single 20-pin (2x10) female connector for both power and data I/O. The power and I/O connector is X501. The manufacturer of this connector is Samtec, part number SFM-110-02-S-D-A.

    10 μF tantalum capacitor (low ESR) with a small (0.1 μF to 1 μF) ceramic in parallel. And the capacitors should put as closer as possible to the NAVIOR-24S VCC pins. The receiver does not require any special power up or down sequencing. The receiver power is supplied through pin 1, 3 of the I/O connector.

  • Page 36: Battery Back-Up

    Note – 2.0 V is the minimum allowable battery back-up voltage. When the battery back-up power output drops below 2.0 V, the real-time clock may not operate over the specified temperature range. This can also significantly extend the time to first fix. NAVIS does not recommend the use of Super Caps as battery back-up.

  • Page 37: Serial Interface

    TTL level serial I/O. The RX and TX signals on the X501 I/O connector are driven directly by the UART on the NAVIOR-24S GPS/GLONASS receiver. Interfacing these signals directly to a UART in your application circuitry provides direct serial communication without the complication of RS-232 or RS-422 line drivers.

  • Page 51: Introduction

    The receiver automatically selects and tracks the best combination of satellites to compute position and velocity. As satellites move out of view, the NAVIOR-24S GPS/GLONASS receiver automatically acquires new satellites and includes them in the solution set as required.

  • Page 52: Gps Satellite Message

    Ephemeris data changes hourly, but is valid for up to four hours. The GPS control segment updates the system almanac weekly and the ephemeris hourly through three ground-based control stations. During normal operation, the NAVIOR-24S GPS/GLONASS receiver module updates its ephemeris and almanac as needed.

  • Page 53: Glonass Satellite Message

    NAVIOR-24S ™ CHAPTER IV Operation and Performance GLONASS Satellite Message Satellite message is transmitted as numerical data flow encoded in Hemming code and converted into relational code. Structurally the data flow is formed as continuously repeated super frames. The super frame consists of 5 frames. The frame consists of 15 data lines.

  • Page 54: Satellite Acquisition And Time To First Fix

    As satellites are acquired, the receiver automatically collects ephemeris and almanac data. The NAVIOR-24S GPS/GLONASS receiver uses the knowledge gained from acquiring a specific satellite to eliminate other satellites, those below the horizon, from the search set.

  • Page 55: Warm Start

    During a warm start, the NAVIOR-24S GPS/GLONASS receiver identifies the satellites which are expected to be in view, given the system almanac, the initial position and the approximate time. The receiver calculates the elevation and expected Doppler shift for each satellite in this expected set and directs the eight tracking channels in a parallel search for these satellites.

  • Page 56: Satellite Mask Settings

    Operation and Performance Satellite Mask Settings Once the NAVIOR-24S GPS/GLONASS receiver has acquired and locked onto a set of satellites, which pass the mask criteria listed in this section, and has obtained a valid ephemeris for each satellite, it will output regular position, velocity and time reports according to the selected protocol.

  • Page 57: Elevation Mask

    NAVIOR-24S ™ CHAPTER IV Operation and Performance Elevation Mask Satellites which are below a 5° elevation are not used in the position solution. Although low elevation satellites can contribute to a lower PDOP, the signals from low elevation satellites have poorer quality, since they suffer greater tropospheric and ionospheric distortion than the signals from higher elevation satellites.

  • Page 58: Standard Operating Modes

    5 m. In this mode an antenna coordinates must be specified and the NAVIOR-24S must be transferred in fixed position mode. It is the most exact mode as only time determination with taking a known position into account executes in the navigation task.

  • Page 59: Dgnss Operating Modes

    Operation and Performance DGNSS Operating Modes The default mode for the NAVIOR-24S GPS/GLONASS receiver is off by Differential DGNSS Operating Mode. The receiver supports two DGNSS Modes: On, Off. The mode may be changed by issuing the appropriate BINR command (see Appendix A for details).

  • Page 60: Position Accuracy

    NAVIOR-24S ™ CHAPTER IV Operation and Performance Position Accuracy Position accuracy is degraded by atmospheric distortion, satellite geometry, satellite clock errors, and receiver clock errors. Effective models for atmospheric distortion of satellite signals have been developed to minimize the impact of tropospheric and ionospheric effects. The impact of satellite clock errors is minimized by incorporating the clock corrections transmitted by each satellite used in the position solution.

  • Page 61: Coordinate Systems

    Operation and Performance Coordinate Systems After the NAVIOR-24S GPS/GLONASS receiver achieves its first fix, it is ready to commence output of position, velocity, and time information. This information is output over serial communication channel in either the BINR or NMEA protocol, as determined by the settings of the receiver.

  • Page 64: Gps/Glonass Timing

    GPS receivers use the signals from these GPS “clocks” to correct its internal clock, which is not as stable or accurate as the GPS atomic clocks. GPS receivers like the NAVIOR-24S GPS/GLONASS receiver output a highly accurate timing pulse (PPS) generated by its internal clock, which is constantly corrected using the GPS clocks.

  • Page 65: Pulse-Per-Second (Pps)

    GPS time from the satellite and is obtaining fixes. The PPS is output immediately after main power is applied, and continues even if the receiver loses GPS lock. The drift of the PPS, when the NAVIOR-24S GPS/GLONASS receiver is not tracking satellites, is unspecified and should not be used for synchronization.

  • Page 67: System Architecture

    Operation and Performance System Architecture The NAVIOR-24S GPS/GLONASS receiver uses 24 processing channels operating on the GPS L1 frequency of 1575.42 MHz and using the coarse acquisition (C/A) code and GLONASS L1 frequency band of 1598,0625…1605,375 MHz and using the coarse CT code . The module uses custom integrated circuitry designed by NAVIS to track the GPS/GLONASS satellite signals.
