# Yellowscan Mapper/ Mapper+/ Surveyor Ultra Gremsy Kit {% hint style="info" %} These intructions can be used with the Yellowscan Mapper, Yellowscan Mapper+, and the Yellowscan Surveyor Ultra. For the purposes of these documentation photos, a Mapper was used. {% endhint %} ## Yellowscan Mapper/Mapper+/Surveyor Ultra Gremsy Kit Installation {% hint style="success" %} Read and follow any **instructions from the manufacturer** prior to installation If there is any contradiction to the following instructions, do not proceed and contact IFT. {% endhint %} {% hint style="success" %} Before proceeding with these instructions, ensure that the **IF800 Midweight Pro Damping Kit is installed on the aircraft**. If not, please refer to the [installation guide](https://docs.inspiredflight.com/inspired-documentation/products/aircraft/if800-tomcat/if800-tomcat-overview/payload-mounting/if800-pro-damping-kits/if800-midweight-pro-damping-kit). {% endhint %} ## Parts Included In this Kit * Smart Dovetail Adapter * GNSS Cable * GNSS Mount * SMA Adapters * Antenna Screws

## Assembling the GNSS Mount 1. Remove the antenna from its packaging

2. Remove the 5 screws on the bottom of the GNSS mount to expose the inside of the mount

3. Thread the antenna onto the GNSS mount

4. Align the 3 holes on the bottom of the antenna with the holes on the GNSS mount. Attach with 3 Antenna screws

5. Replace the 5 screws on the bottom of the GNSS Mount

6. The GNSS mount is now ready to be attached to the IF800

## Attaching the GNSS mount to the IF800 1. Slide the tabs on the GNSS mount into the slots on the drone

2. Push down and thread the thumbscrew to secure the GNSS mount

3. Snap the GNSS MCX connector to the side of the IF800

4. Fully attached GNSS unit appears as shown

## Assembling the Lidar 1. Remove the Lidar, GNSS Cable, and Smart Dovetail Adapter from their respective packaging

2. Align the Smart Dovetail Adapter with the connector on the Lidar via the white indicators, and press onto the lidar. Twist the knurled portion of the Smart Dovetail adapter until the button on the side clicks into place

3. Thread the GNSS Cable onto the SMA connector. The Lidar is now ready to be attached to the IF800

## Attaching the Lidar to the IF800 1. Before attaching the Lidar, release and move the damping plate to the appropriate position on the payload rails, securing the two clamps 1. Yellowscan Mapper should be in position 3. 2. Yellowscan Mapper+ and the Surveyor Ultra should be in position 2.

a) Yellowscan Mapper should be in position 3

b) Yellowscan Mapper+ and the Surveyor Ultra should be in position 2

2. Ensure that the red dovetail clamp is rotated to the released position

3. Align the Smart Dovetail Adapter with the dovetail cage. Slide into the dovetail cage until it clicks into place

4. Rotate the red dovetail clamp towards the rear of the aircraft, locking the payload into place. Adjusting the tension via the screw on the clamp may be necessary to ensure a secure connection.

5. Unthread the SMA cover on the back of the aircraft, and thread the GNSS SMA cable onto the exposed connector 1. Note: The GNSS SMA able may differ visually from the cable shown below.

6. The Lidar is now ready for flight
