The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 or more satellites. Explore Labs GPS Receiver is a 72-channel device based on the uBlox 8th generation chipset that captures those signals and provides accurate location and time information. It has an operating voltage of 3.3V to 5.5V, a high quality ceramic patch antenna on board, and connects to your system via TTL serial broken out on 2.54 cm breadboard compatible pads.
Design Features:
- Upto 18 Hz update rate for GPS-only mode.
- 40 square mm Ground Plane for better antenna gain and directivity.
- External I2C EEPROM for receiver configuration storage
- Backup battery as Supercapacitor for efficient warm start and storage of settings. Currently provides backup time of approx 10 seconds.
- Power Input: 3.3V to 5.5V Input. Or, If connected to an IMU 9 DOF AHRS, may be powered by a Single-cell Lithium Polymer battery.
- 1 TTL UART port @ 3.3V. Use a Logic Level converter in between if using a 5V device like an Arduino Uno.
- Power LED - Red and 1PPS Timepulse LED - Blue
- JST-SH six pin horizontal connector - 1.0mm pitch (EM-406, EM-506 compatibile).
- Dimensions: 40 mm x 40 mm x 8.5 mm
- Weight: 16 gram
- Fully assembled and ready to use.
- Supports direct connection with Explore Labs IMU 9 DOF AHRS.
- Code library: TinyGPS.
