This is a list of GPS Logger Devices that BT747 supports. In general, BT747 supports devices with a MTK/MTK II-Chipset. Even if your GPS is not a logger, BT747 may support GPS Chipset configuration.
BT747 can also upload AGPS (EPO) data if the device supports it (in the 2.X versions). If you want to know where you can buy a logger, you can have a look at "Where can I buy a GPS Logger?". If you have a device that is not listed below but that you find is supported by BT747, do drop me a note (contact form on this site).
Logger devices that use a different logger protocol, but still benefit from some MTK chipset functions (e.g., 5Hz logging). Some untested support may have been implemented:
Standard/other GPS devices (using the MTK chipset) that benefit from part of the functionality of this program (such as setting 5Hz logging).
It is possible to lookup documents in the FCC database through a FCC search page.
