GNSS Min. Lock Time: 0-10 Minutes (Default 0min)
o Minimum time GNSS chip will remain active to achive GNSS Fix/
lock
o Recommended setting is 0min, non 0 value is beneficial in situation
where assets are moving frequently (multiple time in 2h period) as
this will allow full Almanac and Ephemeris data to be received
increasing initial cold lock
time but reducing subsequent hot lock times and optimizing
battery life.
•
GNSS Max. Lock Time: 0-10 Minutes (Default 5min)
o Maximum time GPS module remains active while attempting
to get GPS Fix/lock (Look for available satellites, choose suitable
satellites depending on RSSI values and try to get GPS Fix)
•
DoP Dilution of Precision: Values can be set between 1.0 to 10 with
increment of 0.1
o Default setting of 5.0 for fast lock achieving an accuracy of
5-10m and DOP 3.0 for high accuracy achieving an accuracy of
1-5m.
o Note that the lower the DOP threshold the higher accuracy on
position will be achieved, however, to achieve the higher accuracy
will take longer time and therefore the GNSS max should be set
accordingly.
o Note there is the tradeoff between higher position accuracy, and
battery life reduction due to increased GNSS module up time.
•
Sleep Tag: This function can be used to put Tag to sleep and to
awaken Tag from sleep
o Operation can be executed either by utilising Hall Effect chip
(bringing magnet closer to Top side of LED of Device) or by
PC NFC App.
