2. Operational characteristics

2.1 Initialization

As soon as the initial self-test is complete, the GPS-22 begins the process of satellite acquisition and

tracking automatically. Under normal circumstances, it takes approximately 120 seconds to achieve a

position fix, 42 seconds if ephemeris data is known. After a position fix has been calculated, information

about valid position, velocity and time is transmitted over the output channel.

The GPS-22 utilizes initial data, such as last stored position, date, time and satellite orbital data, to achieve

maximum acquisition performance. If significant inaccuracy exists in the initial data, or the orbital data is

obsolete, it may take more time to achieve a navigation solution. The FirstGPS™ architecture provides

superior performance. However, acquisition performance can be improved as the host system initializes the

GPS-22 in the following situation:

1. Moving further than 1,500 kilometers.

2. Failure of Data storage due to the inactive memory power back up.

2.2 Navigation

After the acquisition process is complete, the GPS-22 sends valid navigation information over output

channels. These data include:

1) Latitude/longitude/altitude

2) Velocity

3) Date/time

4) Error estimates

5) Satellite and receiver status

The GPS-22 sets the default of auto-searching for real-time differential corrections in RTCM SC-104

standard format, with the message types 1, 2, or 9. It accomplishes the satellite data to generate a

differential (DGPS) solution. The host system, at its option, may also command the GPS-22 to output a

position whenever a differential solution is available.

1) All I/Os on the Data Interface are related to VCC (3 to 3.6 Volts) and GND levels.

2) ON/OFF: control the GPS engine “ON” or “OFF”. If this pin is pulled “HIGH” whenever a reset

condition occurs or if it is turned “HIGH” during operating, the GPS engine is turned “ON”. If this pin is

pulled “LOW” whenever a reset condition occurs, the GPS engine is not started. If this pin is turned

“LOW” when in operating, the GPS engine is turned “OFF”. When ON/OFF is “LOW”, the on/off state can

be superseded with the PXEMaRT manufacturer specific NMEA sentence on RXA, as defined below.

3) RXA and TXA: The Serial NMEA data port (RXA and TXA) is an asynchronous serial port (UART).

4) USPED: USPED “HIGH”: 9600 Baud rate, 8 bit data, no parity check, 1 stop bit and no flow control.

USPED “LOW”: 4800 Baud rate, 8 bit data, no parity check, 1 stop bit and no flow control .

This setting can be modified with the PXEMaPT manufacturer specific NMEA sentence defined later.

5) PPS: This is Pulse Per Second highly accurate timing signal generated by the on-board GPS base

band processor at 83ms duration. After a reset condition, the default setting for this port is inactive. This

setting can be modified with the PXEMaPS manufacturer specific NMEA sentence defined below.

6) RESETN: The receiver has 2 reset conditions: first, on power-on, thanks to an on-board Power On Reset

circuitry; and second an external reset when the RESETN pin is “LOW”.

7) VCC: Main power supply.

8) VRTCBK: This is the back-up supply for the on-board real time clock.

9) ALMRDY: When in active mode, this indicates the on-board almanac status. Upon start up and

whenever the almanac data are tested invalid or not up-to-date, the output level is “low”. If tested valid or

up-to-date, the output level is “high”

10) STANDBYIN: This input sets the receiver in stand-by mode when its level is “low”. Otherwise, the

receiver is either in active or power save mode. See below under operating modes for details.
