## Overview

The Holybro mosaic-H is a cutting-edge RTK GPS module that harnesses the power of Septentrio's elite mosaic-H GNSS receiver. It comes with an IST8310 magnetometer, two high-performance antennas, and an aluminum CNC enclosure. It is packed with versatile features such as effortless configuration, spectrum analysis, data logging, and post-processing for a wide range of applications.

With its dual-antenna input, mosaic-H can provide compass-less YAW information to the controller (commonly called GPS Heading or Moving Baseline Yaw). By employing GPS as the yaw source instead of a traditional compass it eliminates the inaccuracies caused by magnetic interference from vehicle motors, electrical systems, and environmental sources like metallic structures or power lines, ensuring precise yaw reports to the controller and enhancing overall navigation reliability and performance in challenging environments.<br>

Septentrio's mosaic-H GNSS receiver module boasts a suite of proprietary technologies that set it apart from the competition. Septentrio’s [AIM+ (Advanced Interference Mitigation) technology](https://www.septentrio.com/en/learn-more/advanced-positioning-technology/aim-jamming-protection) safeguards against intentional and unintentional jamming sources, ensuring consistent and reliable performance even in challenging RF environments.

Septentrio’s [LOCK+ technology](https://www.septentrio.com/en/learn-more/Advanced-positioning-technology/gnss-technology/robust-gnss-signal-tracking) ensures optimal tracking even under rapid antenna displacement in the event of high vibrations or shocks, maintaining high accuracy and stable operation in high-dynamic situations. It is ideal for demanding applications such as UAVs and robotics. Furthermore, Septentrio's advanced [RAIM+ (Receiver Autonomous Integrity Monitoring) algorithm](https://www.septentrio.com/en/receiver-autonomous-integrity-monitoring) delivers unmatched integrity and reliability, providing a safety net for mission-critical applications.

# Setup & Getting Started (ArduPilot)

# Setup & Getting Started (Ardupilot)

## Use as a Rover (Aircraft) Unit

Ardupilot 4.4.0 stable firmware currently also supports Mosaic GPS, but does not yet support dual-antenna Heading. Dual-antenna heading is supported in 4.5.0 and later.

#### FW 4.4.0-4.4.4

To set up using GPS1 input, configure these parameters:

> ℹ️ **Info**
>
> Using serial3 as an example

* GPS\_INJECT\_TO = 0 (send to first GPS)
* GPS1\_RATE\_MS = 100
* GPS1\_TYPE = 10 (SBF)
* SERIAL3\_BAUD = 230
* SERIAL3\_PROTOCOL = 5 (GPS)

To setup this using GPS2 input (serial4) configure these parameters:

> ℹ️ **Info**
>
> Using serial4 as an example

* GPS\_INJECT\_TO = 1 (send to 2nd GPS)
* GPS2\_RATE\_MS = 100
* GPS2\_TYPE = 10 (SBF)
* SERIAL4\_BAUD = 230
* SERIAL4\_PROTOCOL = 5 (GPS)

If you want to inject RTCM corrections to both GPS1 and GPS2, then use:

* GPS\_INJECT\_TO= 127 (send to all)

#### FW 4.5.0+

In ArduPilot 4.5 (or higher), a single unit with two antennas may also be used for GPS for Yaw. If a single unit with two antennas is used, please set the following parameters:

* GPSx\_TYPE = 26 (SBF-DualAntenna)
* GPSx\_MB\_TYPE = 1 (RelativeToCustomBase)
* GPSx\_MB\_OFS\_X and GPSx\_MB\_OFS\_Y, and GPSx\_MB\_OFS\_Z to match the offset of the main antenna from the second in meters. For example, if the second antenna is 50cm to the right of the main antenna, set GPSx\_MB\_OFS\_Y.
* EK3\_SRC1\_YAW = 2 (GPS)

### Antennas Setup&#x20;

In addition, both antennas (“Master” and “Slave”) must be attached and positioned at least 30cm apart. The location of the vehicle is flexible, but their positions impact several parameters which must be set in order to obtain proper operation. These offset distances in the x/y/z directions must be entered for the following parameters:

* GPS1\_MB\_TYPE = 1 (GPS1 Moving Baseline master antenna offsets relative to slave antenna, also enables the next parameters to be shown)
* GPS1\_MB\_OFS\_X: offset in meters from the "Slave" to "Master" antenna in the X axis (in direction of 0 deg yaw, positive offsets are if "Master" is in front of the "Slave".
* &#x20;GPS1\_MB\_OFS\_Y: offset in meters from the "Slave" to "Master" antenna in the Y axis (in direction 90 deg (right) of 0 deg yaw, positive offsets are if "Master" to the right of the "Slave".
* GPS1\_MB\_OFS\_Z:: offset in meters from the "Slave" to "Master" antenna in the Z axis (in direction up and down, positive offsets are if "Master" is below the "Slave".

This figure and photo illustrate these parameters and their settings:

## Implement RTK through MissionPlanner

> ⚠️ **Warning**
>
> This section only applies to mosaic-H

Connect the Mosaic-H GPS to the computer via the USB port. After Mosaic-H is connected to the computer, there will be two Virtual USB COM Ports. Virtual USB COM Port 1 corresponds to USB1 in the operation interface, and Virtual USB COM Port 2 corresponds to USB2. Generally, we use USB1 to transmit NMEA/GGA and other data, and then on USB2 output RTCM data. With the MissionPlanner auto configuration feature, both COM ports can be used for the RTK base function.

On the missionPlanner-> SETUP-> Optional Hardware-> RTK/GPS Inject page, make sure Automatically Configure Receiver is enabled, and the Septentrio option is selected. Choose any of the mosaic-H's COM ports and click Connect.

> 🖼️ _[Image — to be added]_

When Mosaic-H is used as a Base station, it will automatically select the appropriate positioning accuracy based on signal quality. There is no need to set the accuracy and survey-in time.

When the Base, GPS, Glonass, Beidou, and Galileo icons in the RTCM column all turn green, the ground station begins to send the RTCM data to the flight control through digital transmission.

Click on the MissionPlanner->DATA page, and you can see that the rover side has been RTK-Fixed. (The rover side can use F9P or Mosaic-H)

> 🖼️ _[Image — to be added]_

Now return to the Mosaic-H configuration page, click on the NMEA/SBF Out page, and you can see that the USB2 port has started to output the RTCM data stream.
