There are various modes which Activity Sense can be set using the iOS app TP Connect to change it's configuration. When the specific activity is detected then the unit will use the Burst Mode tracking settings, when the activity is not detected then it will use the standard tracking frequency setting.
We find the Activity Sense features very helpful and will set our standard tracking settings as our slow/sleep rate and the burst tracking settings as our fast/awake tracking rate.
The 4 Activity Senses
There are 4 specific Activity Sense modes that can be used. They cannot be used together in conjunction with each other.
The ‘Threshold’ setting is used for the Bump Activity Sense and has no relevance to Power and SOG modes. This is related to how sensitive the device is to getting bumped round. The manufacturer recommends a setting somewhere between 20 and 30 for good result.
‘Bump’ will use the accelerometer to detect bumps or vibration, and will activate the burst mode whilst it's bumping. Once stationary and no bumping or vibration is detected it will revert back to it's standard tracking settings.
‘SOG’ (Speed Over Ground) will turn on the GPS chip all the time, and activate burst mode when ‘SOG’ is over 6 mph (4 Knots or 11 km/h), but this setting will use a lot of battery as the GPS chip is permanently powered. It will switch back to your standard tracking settings when the speed drops below 2.5 mph (2 Knots or 3.7 km/h).
Bump + SOG:
‘Bump + SOG’ is mixture of ‘Bump’ and ‘SOG.’ When the unit detects bumping, vibration or speed; it will turn on GPS and begin transmitting positions using the burst mode settings. It will remain in burst mode until both; ‘SOG’ goes below 4 mph, and the bumping stops and then it will revert to your standard tracking settings.
In ‘Power’ mode the unit will use the external power status to trigger switching between standard tracking and your Burst tracking settings. If the unit detects external power it will transmit position messages using the burst mode settings and if the power is off the unit will use the standard tracking settings.
Examples of Use:
‘Bump’ is good for walkers, and something which is continuously bumpy, such as a 4x4 car.
‘SOG’ is good all the time, but uses a lot of power as it has to have GPS on all the time. Good for permanently powered installations.
Bump + SOG:
‘Bump + SOG’ gives optimum power usage when the vehicle (plane or whatever) initially is bumpy on tarmac to activate it, but then in cruise is smooth (and so needs the ‘SOG’ mode to keep burst going).
Power - Good for when connected to the car ignition/avionics master/vessel batteries/USB port for example, so will transmit in burst mode when the car/aircraft/vessel is powered up and 'on'.
