Thinkstar USB GPS Receiver

The Thinkstar USB GPS Receiver is a 56-channel GNSS antenna designed for laptop, PC, car, marine and Raspberry Pi navigation. It uses a U-BLOX UBX-G7020 chipset with -162 dBm tracking sensitivity and supports NMEA 0183, WAAS, EGNOS, MSAS, QZSS and GAGAN protocols. The device connects via a standard USB port with a 2 metre cable and features a magnetic base with IPX4 water resistance. It is powered directly from the USB port and works with U-CENTER evaluation software.

Who this suits and who it does not

This receiver suits users needing a plug-and-play GPS antenna for Windows 98 through Windows 11, Raspberry Pi with gpsd, or marine charting software such as OpenCPN. It is not for buyers who require an internal PCIe or M.2 form factor, devices with built-in data logging storage, or multi-constellation receivers supporting L2 or L5 band signals. The magnetic mount also limits permanent through-hole installations.

U-BLOX UBX-G7020 chipset

The single specification that decides compatibility is the U-BLOX UBX-G7020 chipset providing 56-channel all-in-view tracking at -162 dBm sensitivity. This determines the satellite constellations received, the NMEA 0183 protocol output, and the USB serial interface used by U-CENTER V8.2X software. The 2 metre cable length and IPX4 rating define the physical installation envelope for automotive or marine use.

Questions about this item

Does my computer need a free USB-A port to connect this GPS receiver?

Yes, the device plugs directly into a USB-A port and draws power from it, so a spare port is required.

Will the magnetic base hold the antenna firmly on a steel vehicle roof at highway speed?

The magnetic base is designed for automotive mounting and stays attached on steel surfaces during normal driving.

How can I confirm the receiver is outputting valid NMEA sentences after I install U-CENTER V8.2X?

Open U-CENTER, select the correct COM port, and watch the NMEA 0183 stream populate with latitude, longitude and satellite count.
