A GPS tracker does not always send every position through a separate connection. Depending on the model, coverage, and operating behavior, it may group several messages and transmit them together. This update enables Secure GPS to process multiple GT06 positions or events contained in one transmission.
The improvement helps preserve a more complete sequence of activity reported by the device and expands compatibility with trackers that use the 0xA0 position variant of the GT06 protocol.
Why a tracker may group several messages
Trackers usually report a position at configured intervals. However, an unstable mobile connection, a period without coverage, or the device's own behavior may cause several messages to remain pending and be sent together when communication becomes available again.
Some devices also concatenate information by design to use a single transmission. In those cases, the received block may contain several complete packets, each with its own header, length, message type, content, and verification data.
If a platform interprets the entire block as one packet, it may recognize only one part or discard the remaining information. Each message must therefore be separated before its location or event can be interpreted.
Processing multiple GT06 packets
Secure GPS now identifies consecutive GT06 packets that use the 0x7878 header, reads the declared length of each packet, and processes them individually. A separate record is created for every message containing valid information sent by the tracker.
This makes it possible to retain several positions received together and respond to the device after processing the sequence. The function does not create intermediate points or change the reported time: it uses the messages that actually arrived from the equipment.
For an operator, the result can be a more continuous route history when a tracker reconnects and delivers accumulated information. For an installer, it provides better compatibility with GT06 models that group packets in one communication.
New support for GT06 position type 0xA0
The same release adds message type 0xA0 as a valid GPS position variant. When a compatible tracker uses this format, Secure GPS can interpret data such as date, time, satellites, latitude, longitude, speed, and heading included in the packet.
This support expands the hardware options that can communicate correctly through GT06. However, sharing a protocol name does not guarantee identical behavior across all models: some manufacturers change fields, lengths, or events.
Before deploying many devices, an integrator should test the specific model, verify that its identifier is accepted, confirm that coordinates and dates are correct, and check the response after several messages are sent together.
Benefits for history, alerts, and reports
When more valid positions are retained, route history can represent the completed journey more accurately. This helps users review where a vehicle traveled, how long it remained in an area, and the order in which tracker events occurred.
The sequence also provides context for available alerts and reports. For example, if a device loses coverage during a route and later transmits several positions, a fleet manager can reconstruct that period instead of seeing only the last point received.
Accumulated data is not the same as live tracking: an older position continues to appear with the time reported by the tracker. This distinction helps users understand whether the vehicle is currently transmitting or delivering activity recorded earlier.
Applications in real operations
A transportation company traveling through rural areas may receive several points after mobile coverage returns. A security company can preserve the order of events recorded during an interruption. A technician can use a multiple-transmission test to validate a batch of trackers before installation.
In every case, usefulness depends on the device storing and sending valid messages. Secure GPS processes the received sequence and integrates it with map, route history, zones, alerts, and reports.
Technical summary for installers and integrators
- Several concatenated GT06 packets with the 0x7878 header can be recognized in one transmission.
- Each packet is separated according to its length and processed as an independent position or event.
- Support was added for GPS position type 0xA0.
- Dates and data remain as reported by the tracker; accumulated positions are not presented as current positions.
- Final compatibility depends on the manufacturer's implementation and should be validated with the specific model.
From the Secure GPS device menu, you can review tracking and route history for each tracker. See Secure GPS plans and features for the capabilities currently available.
