=== PGRMT - Garmin Proprietary Sensor Status Information ===
|
|
|
|
The Garmin Proprietary sentence $PGRMT gives information concerning the status of a GPS sensor. This
|
|
sentence is transmitted once per minute regardless of the selected baud rate.

Field Number:
|
|
|
|
1. Product, model and software version (variable length field, e.g., “GPS 10 SW VER 2.01 BT VER 1.27 764”)
|
|
2. ROM checksum test, P = pass, F = fail
|
|
3. Receiver failure discrete, P = pass, F = fail
|
|
4. Stored data lost, R = retained, L = lost
|
|
5. Real time clock lost, R = retained, L = lost
|
|
6. Oscillator drift discrete, P = pass, F = excessive drift detected
|
|
7. Data collection discrete, C = collecting, null if not collecting
|
|
8. GPS sensor temperature in degrees C
|
|
9. GPS sensor configuration data, R = retained, L = lost
|
|
|
|
Note: Some sensors have been seen to not provide all information above, in some cases just the product
|
|
model during boot. Example:
|
|
|
|
$PGRMT,GPS19x-HVS Software Version 2.20,,,,,,,,*6F
