- Available with a lead time — expect dispatch between Sep 01 and Sep 07.

## Restrictions

**For use in Australia**

- Operate only in bands and with settings that are permitted for your location and application. Check this product’s supported frequencies in the description/specs.
- If you intend to operate outside shared/licence‑exempt conditions (e.g. in other bands, at higher power, with high‑gain antennas, or extended duty cycles), you must have the appropriate authorisation.
 
**For use in other regions**

- Follow the spectrum rules for your country/region and select frequencies and settings accordingly.

A declaration of use will need to be submitted during checkout.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=KIT0198-US:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/KIT0198-US:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

The **LoRa-Based** GNSS-RTK High Precision Positioning Kit (US) is a comprehensive, dual-module system engineered to deliver centimeter-level location accuracy. It operates on the principle of Real-Time Kinematics (RTK), which involves a stationary base station transmitting correction data to a mobile rover, effectively eliminating common GNSS positioning errors. The kit's key differentiators are its out-of-the-box functionality with a pre-configured LoRa data link, its high-performance dual-band GNSS reception, and its rapid convergence time. Powered by Quectel LC29H series modules, the system **supports GPS, GLONASS, Galileo, BDS, and QZSS constellations**, making it a robust solution for demanding applications such as autonomous vehicle navigation, land surveying, and device tracking.

**Out-of-the-Box, Centimeter-Level Accuracy**

This GNSS-RTK positioning kit is designed to significantly lower the barrier to entry for high-precision positioning. Traditional RTK systems often require users to independently source and configure separate modules for the base, rover, and data transmission link. This product integrates all necessary components into a pre-configured, ready-to-use solution. Users can achieve centimeter-level accuracy within minutes of setup, bypassing the complex integration and debugging process typically associated with RTK technology.

**High-Performance Dual-Band GNSS Engine**

At the core of the system are the Quectel LC29H series modules, which feature dual-band (L1/L5) reception. This advanced capability allows the receiver to effectively mitigate ionospheric disturbances, a primary source of error in single-band receivers. The result is a significantly faster convergence time (less than 10 seconds to achieve a fixed solution) and more reliable and consistent positioning accuracy, even in challenging signal environments. Simultaneous tracking of all major satellite constellations ensures maximum satellite availability and positional integrity.

**Integrated Long-Range LoRa Data Link (915 MHz US Version)**

A stable data link is critical for RTK performance. This GNSS-RTK positioning kit incorporates a LoRa (Long Range) radio communication system to ensure robust and reliable transmission of correction data from the base station to the rover. This integrated wireless solution provides a communication range of up to 1.5 kilometers in open areas, eliminating the need for external radio modems or reliance on internet-based NTRIP services. This self-contained architecture makes the kit ideal for fieldwork and applications in areas with limited network connectivity.
