5 GEOLOCATION STRATEGY MODES

5.1 Main operatng modes and SOS mode

The folloting geolocaton technology setng (

geoloc_sensor

parameter)

are used by the operatng

modes: motonitracking, permanentitracking, start/end tracking and SOS. Note that in standby
mode, only side operatons can report positons.



WIFI only

→ Only WIFI scans are used for positon determinaton.



GPS only

→Only the GPS is used for positon determinaton.



LPGPS only

→ GPS and lot poteriGPS are used for positon determinaton.



Mult-technologies modes

o

WIFI-GPS only

→ WIFI then GPS if WIFI fails in one geolocaton cycle.

o

WIFI-LPGPS only

→ WIFI then Lot poteriGPS if WIFI fails in one geolocaton cycle.

o

WIFI + LPGPS + GPS

→ Alternate WIFI, LPGPS and GPS technologies on failure, tith

tmeout.

Superseded by WIFI-LPGPS/ WIFI-GPS

mode.

o

WIFI-LPGPS/ WIFI-GPS

→ WIFIilot poter GPS frst, then WIFIiGPS if WIFIilot

poter GPS fails untl tmeout, then back to WIFIilot poter GPS.

5.2 Side operatons

The folloting geolocaton technology setng (

geoloc_method

parameter) are used for periodici

reportng, onidemand or alert operatons.



WIFI only

→ Only WIFI scans are used for positon determinaton



GPS only

→Only the GPS is used for positon determinaton



LPGPS only

→ GPS and LPGPS are used for positon determinaton



Mult-technologies modes

o

WIFI-GPS only

→ WIFI then GPS if WIFI fails in one geolocaton cycle

o

WIFI-LPGPS only

→ WIFI then lot poteriGPS if WIFI fails in one geolocaton cycle

5.3 Geolocaton technology descripton

5.3.1

Positon message scheduling

The positon message reportng frequency is based on the

ul_period

parameter. Hotever, the frst

message can be postponed dues to the positon acquisiton delay.
This delay depends on the geolocaton strategy used.
Nonetheless, the tracker triggers an uplink message each tme a net geolocaton cycle starts. This
message depends on the operatng mode used and the

config_flags

confguraton

Afer the transmission of this inital message, a frst positon is transmited tith the folloting delay:



GPS, or WIFIiGPS: the

gps_timeout

parameter is used. See GPS secton to have details about

the tmeout used)



LPGPS, or WIFIiLPGPS: the

agps_timeout

parameter is used.



WIFI only: the tmeout is fxed to 10 seconds.
