Key Features & Specifications
1. Multi-Band, Multi-Constellation Reception:
* Constellations: It can receive signals from all major global satellite systems simultaneously:
* GPS (USA)
* GLONASS (Russia)
* Galileo (EU)
* BeiDou (China)
* QZSS (Japan)
* SBAS (WAAS, EGNOS, etc.)
* Frequency Bands: It uses L1 + L5 frequency bands. This is the key to its high accuracy. Receiving two frequencies allows themodule to correct for signal delays caused by the Earth's ionosphere
2. High Precision & Accuracy:
* Standalone (SBAS): ~1 meter
* With RTCM Corrections (RTK): ~1 cm + 1 ppm horizontally
* With RTCM Corrections (PPP): ~10 cm
3. Correction Services & Technologies:
* RTK (Real-Time Kinematic): This is its primary mode for centimeter-level accuracy. It requires a stream of correction data from a base station (either your own or a paid/caster service like NTRIP) via a communication link (e.g., cellular)
* PPP (Precise Point Positioning): A method that uses correction data from global networks, which can be delivered via satellite(e.g., SPARTN protocol for u-blox's PointPerfect service). It offers decimeter-level accuracy without needing a local base station.
4.High Performance Specs:
* Max Navigation Update Rate: Up to 25 Hz (25 times per second).
*Time-To-First-Fix (Cold Start): ~26 s.
*Dual Antenna Support (Option): Some configurations support a second antenna for determining heading directly, which is excellent for vehicles and drones.
5. Interfaces:
* UARTs (x4): For configuration, data output, and receiving correction data.
* USB 2.0: For easy connection to a computer.
* I2C: For connecting to other sensors or peripherals.
* SPI: For high-speed communication.
* DDC (I2C-compatible): For connecting u-blox GNSS chipsets together.
*CAN: For robust communication in automotive/vehicle environments.
