5.2.3.2 "Proprietary Motion Activated Track" command
This command allows the initiation of a periodic track with user defined data prepended and appended to the latitude
and longitude fields. A periodic 9-byte custom track message, transmitted nominally at the interval specified, will result.
The mode of operation will be determined by the Tracking Preferences:
1. Continous Tracking
2. Motion Activated Tracking
3. Motion Activated Tracking with Dock mode
In track mode, the STINGR does not send bursted (redundant) messages. It will transmit a single transmission for each
interval. If it is desired to send bursted messages, use the Send Data (0x00) or Send Redundant Burst with GPS (0x33)
commands. While in Proprietary Track mode with an interval of 30 minutes or less, the GPS will retain its clock and
ephemeris data in order to perform a "hot" GPS fix. This will increase the GPS standby current to the "GPS Standby
Mode" value in Table 4. For tracking intervals greater than 30 minutes, the GPS will be powered off in between
transmissions and the sleep current will be the "Standby Mode" value in Table 4. While in Motion Activated Track
mode, the accelerometer sub-system will remain powered during the standby periods in between transmissions and the
accelerometer standby current will be will be the "Standby mode supply current w/Accelerometer" value in Table 4.
