Its onboard 4G module receives RTCM correction data from a CORS network via the Ntrip protocol, removing the need for a local base station when CORS coverage and 4G signal are available.The receiver tracks GPS, GLONASS, Galileo, BDS and QZSS, with multi-band support to help reduce ionospheric interference and multipath effects. It can converge in under 10 seconds and outputs positioning data through a flexible Gravity interface with selectable I2C or UART for microcontrollers and single-board computers.Deployment is centred around inserting a 4G SIM card and configuring the unit with CORS account credentials. The kit includes the RTK Mobile unit, GNSS antenna, 4G/LTE right-angle rubber duck antenna, flathead screwdriver, plug-in terminal block and a 30cm PH2.0-4P connection cable. DFRobot also provides a product wiki for setup information.Features:Network RTK over 4G: Receives RTCM correction data from a CORS network via Ntrip.Centimetre-level positioning: Delivers 5 cm + 1 ppm accuracy over a typical 15-20km operational range.No local base station required: Uses an established CORS network instead of a 3-5km local radio link.Multi-constellation GNSS: Supports GPS, GLONASS, Galileo, BDS and QZSS.Multi-band reception: Supports bands including GPS L1/L5, Galileo E1/E5a and BDS B1l/B2a.Fast convergence: Achieves convergence in under 10 seconds.Gravity interface: Selectable I2C and UART signal outputs for project integration.Autonomous Rover: Build a rover, autonomous lawnmower, or delivery bot that navigates with pinpoint precision.Asset Tracking: Create a high-precision tracker for fleet vehicles, expensive equipment, or even a lost drone.Data Logging: Map a precise trajectory, conduct simple land surveys, or create a set of fixed monitoring points for science projects.Outdoor Robotics: Give any outdoor robot a reliable, centimeter-level understanding of its position in the world.Specifications:Power Interface: Gravity interface, 3.3~5VType-C: For 4G module power (requires separate power supply)Output Signal: I2C / UARTAntenna Interface: SMAReception Bands:GPS/QZSS: L1 C/A, L5GLONASS: L1Galileo: E1, E5aBDS (BeiDou): B1l, B2aDefault Constellations: GPS + GLONASS + Galileo + BDS + QZSSConcurrent Tracking Constellations: 4+ QGNSSSBAS: WAAS, EGNOS, MSAS, GAGANFunction: RTKHorizontal Positioning Accuracy:Autonomous: 1 mRTK: 5 cm + 1 ppmVelocity Accuracy: 0.03 m/s1PPS Accuracy: 20 nsRTK Convergence Time: < 10 sSensitivity:Acquisition: -145 dBmTracking: -165 dBmReacquisition: -157 dBmDynamic Performance:Max Altitude: 10000 mMax Velocity: 500 m/sMax Acceleration: 4 gNavigation Update Rate (RTK): 1 HzRaw Data Output Rate (GNSS): 1 HzProtocol: NMEA 0183 / RTCM 3.xWeight: about 380gSupported Countries/Regions: EMEA & ThailandFor best results, use it outdoors away from tree shade, bridges and strong electromagnetic interference. The 4G module requires separate Type-C power and should be powered first; check CORS account coverage before setup. **Product Type:** GNSS RTK Kit ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDbUkBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--3758316889d75bf33861d9c2e7bd2f68e077b543/KIT0212_ShipList_05.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDc0kBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--161397943504b924179655d4f24614f17bd1f2e1/KIT0212_Dim_02.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDe0kBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--a49789c64f120a960026455df45644befb095676/KIT0212_Back_03.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDgUkBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--e4773676d97c86823c82b5c414d4b562ce85ed20/KIT0212_Detail_04.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDikkBSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--944c0f565ed9099be50ac568da9acd443926c5e4/KIT0212_Detail_06.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
