Holybro H-RTK Unicore UM982 Dual Antennen GPS RTK Modul - 12036

Das Modul ist die Neuentwicklung von Holybro (06-2023) und ist speziell dafür vorgesehen mit nur einem GPS Modul GPS Heading (Moving Baseline Yaw) durchzuführen, was eine Navigation ohne Kompass ermöglicht.

Hierzu sind KEINE zusätzlichen RTK Korrekturdaten notwendig, die Berechnung erfolgt rein über die beiden Antennen.

Das Modul kann mit allen gängigen Flightcontrollern (z.B. Holybro Pixhawk 6X,  6C, 6C Mini, HEX Cube Orange, HEX Cube Orange+, uvm.)

**Abmessungen Board:** 34,8 x 58,9 x 14,4 mm

**Abmessungen Antenne:** Durchmesser: 27,5mm - Höhe 59mm

**Gewicht:** ca. 37,9g (ohne Antenne)

&#x20;

### **Ausführliche Informationen:**&#x20;

The Holybro UM982 Dual Antenna RTK GPS provides high-precision positioning information and is capable of generating non-magnetometer moving baseline yaw determinations for autopilots with one single GPS module.&#x20;

One of the best applications of this GPS is to provide compass-less YAW information to the autopilot (commonly called GPS Heading or Moving Baseline Yaw). Using this GPS as a yaw source prevents magnetic interference from the vehicle motors and electrical systems and any environmental interference sources, such as metallic structures or equipment, that can cause incorrect yaw reports to the autopilot.

This works even if the GPSs are not receiving RTCM data from a fixed RTK station or NTRIP server. The device is based on the Unicore UM982 NMEA GNSS module and supports RTK positioning adjustment for centimeter-level accuracy, GPS/GLONASS,Beidou, Galileo, and QZSS global positioning systems.

It also includes a magnetometer, LED, and safety switch button. It also serves as an RTK-corrected vehicle GPS, with or without moving baseline yaw determination, and as a base station GPS for sending RTCM data to a ground control station to provide an RTK source for the vehicle via telemetry.

&#x20;

**Features**

Dual antennas allow Moving Baseline Yaw (GPS Heading) with just one module

Can replace the traditional compass/magnetometer

Perfect for system/environment with high magnetic interference

Excellent RTK performance

Tips: It is recommended to use the H-RTK F9P-Base orF9P Helical as your base station because it's simple setup procedure in Mission Planner & QGroundControl. Neither MP nor QGC can configure the UM982 automatically as base station at this moment, additional manual setup is required.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.premium-modellbau.de/premium-modellbau-portal-fuer-anleitungen/holybro/holybro-ubersicht/holybro-gps-module/unicore-um982/unicore-um982-dual-antennen-gps-rtk-modul-12036.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
