Accuracy and Limits
Each source has a different precision. A GPS fix can be accurate to a few metres; a cell connection may only place a device within a wide area. We report the accuracy of each record, where sources agree or conflict, and what the evidence cannot establish. That is what lets a finding survive cross-examination.

Common Questions
How accurate is phone location data?+
It depends on the source. A GPS fix can be accurate to a few metres, while a cell tower record may only place the phone within a wide area. We report every location point with its source and likely accuracy.
Can you show where a phone was at a specific time?+
Often, if the phone or a linked account recorded its location around that time. Gaps are common, and the report states clearly where the data cannot place the device.
Does a phone’s location prove where the person was?+
No. It shows where the device was. Whether the person had it with them is a separate question, and we look for activity on the phone that helps answer it.
