The Remora has two main tracking modes, the first of which has an optional extra feature for small movement updates. This flexibility allows you to enhance reporting, minimise battery consumption, and cater for niche applications. To help you can choose an appropriate tracking mode, an overview of each mode's operation is provided below.


GPS Tracking Mode – The normal mode that tracks trips well

· Accelerometer wakes unit, or unit wakes on timer every few minutes if it is tired of being woken up all the time

· On each wake, it gets a GPS fix

· It tries to figure out if it is in trip by looking at the fixes

· Once it thinks it’s moving, it enters a trip

o Once in-trip, the accelerometer is turned off

o It wakes up every few minutes on a timer and gets a fix

o It checks if the trip is still in progress by looking at the fix

o When the fixes suggest movement has stopped, it exits the trip

· Uploading can happen before, during, and after the trip, optionally

· Heartbeats happen if there has been no upload for a long time

 

Jostle Based Tracking – For special requirements (run-hours, tracking small trips)

· Accelerometer wakes units

· Unit immediately enters trip

o Once in trip, the accelerometer no longer wakes the unit

o It wakes every two minutes on a timer, and does two things

§ Asks the accelerometer if there was any movement in the last two minutes

§ If it is time to log a position, it gets a fix and records it

o Once the accelerometer claims there has been no movement for a while, and the GPS doesn't show movement, the trip ends

o The trip can continue even if the GPS isn't showing movement, so long as the accelerometer is 

· Uploading can happen before, during, and after the trip, optionally

· Heartbeats happen if there has been no upload for a long time

· The purpose of this is to allow trips to be recognized regardless of the size of the motion

· It is much less robust than GPS tracking mode at rejecting false trips – so only useful for things like run hours, or tracking tiny trips

 

Jostle Uploads – For locating an asset after small movements in a yard

· Jostle Uploads is an extra option for GPS Tracking Mode

· GPS Tracking Mode will take care of locating the asset in-trip, but normally doesn’t provide any small-movement updates once the trip ends. So if you drive your car to work, it tells you it’s at work. But when you move it to a parallel street once your parking expires, it normally doesn’t update.

· Jostle Uploads schedules a heartbeat after any small motions are detected out-of-trip.

· The heartbeat updates the live view, showing that your car has moved to the parallel street, even though that small movement didn’t constitute a trip.


To configure a Remora to use Jostle Based Tracking, set Jostle Based Tracking = Yes in the Advanced Tracking tab of the Edit System Parameters dialog on OEM server.
