7 Examples of configuration
7.1 Accurate position using GPS mode only
Case description:
Accurate Motion tracking of an asset. Configuration:
✓ Environment: outdoor only (GPS mode only).
✓ Reporting position period: 5 minutes.
✓ LoRa TX strategy: Dual transmit with random SF when moving.
✓ No power consumption restriction
To improve the GPS accuracy, you can either decrease gps_ehpe parameter or increase the gps_convergence
time.
The GPS timeout can be also modified to let more time to have or refine a position.
Proposed configuration
✓ Operational mode: motion tracking
✓ ul_period: 300 (5 minutes)
✓ geoloc_sensor: 1 (GPS only)
✓ gps_timeout: 290s.
✓ gps_ehpe: 3m
✓ gps_convergence: 120s
✓ gps_standby_timeout: 3600s (1 hour)
✓ transmit_strat=2
Results:
Accurate GPS positions are obtained each five minutes under good condition (weather, …).
7.2 Low power configuration,
Case description:
Long battery life time, with position only when desired.
✓ Single position on request.
✓ High position cadency on request
✓ Environment: indoor/ outdoor
Proposed configuration
✓ Operational mode: Standby
✓ geoloc_method: 4 (WIFI/ A-GPS)
✓ transmit_strat=2
✓ Downlinks:
o Receive position of the device (position on demand
o Activate the SOS mode to accurately track the device.
Results:
✓ Single position: When requested, the position is sent twice (it is doubled if the device is moving).
✓ Continuous positions (each 120s using WIFI/GPS) until the SOS mode is stopped.
