What does it take to create a drone for completing WISP site surveys?

The payload of the drone is affected by the customer premise equipment antenna (CPE). The CPEs used by WISP have many variations in size and dimensions. The surface area of every CPE introduces additional wind drag on the drone. According to FAA 107 regulations, legal takeoff weight of a drone in the USA is 55 lbs. To safely operate a drone and carry a CPE antenna the drone must be able to handle at minimum 30 lbs. over the weight of the CPE.

With 5-10MPH winds the CPE antenna’s wind drag can create 10-15 lbs. of added weight to the drone’s payload. This is why we have a 10 lb. payload limitation on the WISPr Scout, even though it can handle a takeoff weight of 55 LBS (that’s including the weight of the battery and Scout).

Figure 1 shows an example of the surface area introducing the wind drag.

The drone needs to have undercarriage space to mount the CPE. Most CPE are either 6.4"-12", so having the appropriate undercarriage space is critical to flying with the CPE.

Note: 400 dishes are 15.8”, WISPr Systems has an upgraded landing gear that can be purchased.

The illustration shows an example of the undercarriage space.

The drone’s thrusters (motors) need to be placed high enough above the drone’s payload to naturally force the payload to stay level. This assists the machine-learned processes to increase the stability of the drone. Only the WISPr Scout and the DJI Inspire have this type of placement for the motors. The DJI Inspire is not designed to carry a payload so it is not used in this comparison.

The illustration shows an example of the motor placement.

The drone needs a power over ethernet (POE) port to power the CPE and software to operate the drone and communicate with the CPE so the user can easily view the CPE software and run site surveys.

Scout's altitude is sensed by a barometer and a LiDAR (Light Detection and Ranging) for altitude accuracy within ±2 cm for altitude and vertical control.

A first person view camera comes pre-installed to give the user a 1080p birds-eye view from Scout.
