| Q. |
How do I know if the module is operating correctly? |
| A. |
A GPS fix within 120 seconds will show the unit has a reasonable signal, and is working. The signal levels of each satellite can be measured using the Labmon Analyser PC software and a comport serial adapter. Satellite signal levels should be in the range 35 to 48 dBHz. |
| Q. |
What supply voltage must be used? |
| A. |
The Jupiter Pico supply and I/O must always be limited 3.3 VDC. |
| Q. |
How long does the unit take to get a GPS fix? |
| A. |
The unit will normally get a GPS fix within 120 seconds from a cold start. |
| Q. |
What is the format of the output data? |
| A. |
The Jupiter Pico default data protocol is Navman binary at 9600 baud. However NMEA (a standard protocol for marine electronics) is also available. Most GPS software applications use NMEA as their input. |
| Q. |
How does the active antenna get power? |
| A. |
The antenna connection of the Jupiter Pico can have a DC voltage imposed upon it for power to the active antenna. This voltage can be applied to pin 1 on the data connector. Note: if a passive antenna with an inherent DC short is used this supply should not be applied. |
