Is it really free?
Yes, with the following caveats.
- We provide little or no support other than that on the forums
- We don’t provide any uptime guarantee but we’ll do our best to keep the servers online
- We operate an aggressive data purging policy to ensure that inactive users and devices are removed
Do you have a timeline? What’s coming next?
We do, it’s here. If you have any suggestions please raise them in the relevant section in the forum.
I’m new to GPS tracking, I want to track my car. What tracker do you recommend?
TODO: List trackers & recommendations
What GPS trackers will work?
We support a number of different tracker protocols (protocol – the way the tracker talks to the server). We *do not* support all features of all protocols. A lot of trackers can be configured in different ways and this results in different sets/types of data ending up at latlng. Our aim is to support enough of the protocol to allow the tracker to connect to latlng and show positions on a map. The better quality trackers will be able to provide ignition status (or moving status) and from this we can process your data into journeys.
What support do you provide?
All support is provided via the forums via the community.
How long are my positions stored?
If you have a free account, positional data for each device is normally stored for 7 days. This setting can be seen on the device properties. Data older than 7 days is automatically purged.
Purged data is permanently deleted and cannot be restored.
What other data is automatically purged?
In order for us to keep the system to a manageable size, other types of data are automatically purged.
- Devices are deleted if they are inactive. Inactive devices have no historical positional data and no changes for the last 30 days
- Users are deleted if they are inactive. Inactive users have not logged into the system in the last 30 days. A user will receive 2 warning emails before their account is deleted.
- Groups are automatically deleted if they contain no Users and no Devices. Any other group content that isn’t a member of another group will also be deleted
Purged data is permanently deleted and cannot be restored.
What is valid GPS data?
Latlng will only accept valid GPS data. Amongst others, the following basic rules will be applied to all incoming data.
- Datetime – must be no more than 7 days old
- Datetime – must not be in the future
- Latitude and Longitude – must be valid and not both 0
- Datetime and event type – must not be the same as last valid packet
- Calculated speed (using position and time) between last packet and new packet is more than XX
Any packets that contain non valid GPS data are discarded (after sending the necessary ACK to the device)
