USB GPS Receiver
Great little receiver - connected to a Pi4 and a Pi5 for use with Kstars/Ekos ... no issues at all. 3-5min to get a fix but was accurate to within 10m ..compared to Google Maps.

This GPS receiver brings much more accurate and faster positioning performance with stronger signal compared with traditional GPS receivers. It is compact, lightweight and portable. Integrated with built-in receiving antenna, this product adopts a high-precision positioning chip and industrial-grade manufacturing process so that it can meet the positioning requirements of both industrial-grade and personal use. The GPS receiver has battery inside for supplying power for storing satellite data, such as satellite signal status, final position and time that would greatly increase the positioning speed at the module’s next boot. In addition, this receiver adopts USB interface, which can be conveniently used in maincontrollers like Raspberry Pi, NVIDIA,LattePanda. It is suitable for vehicle navigation, handheld positioning, wearable devices and other fields.

Jargon buster
Plain-language definitions for the technical terms used above.
- baud
- Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
- GPS
- The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.
- SBAS
- Satellite-Based Augmentation System, a set of regional services that broadcast correction information for GNSS receivers. SBAS can improve ordinary GPS-style positioning, although it is not the same as centimetre-level RTK correction.
