Why an Experimental License is Necessary:
An experimental license is required to test and operate a Merlin-Harrier RADAR system. This radar will
be used as a surveillance radar.

Operation Description:
The request for license approval is based on the need to test UAS ground based detection system
radars, ADS-B, and Mode-C sensors packages that will provide air picture awareness only inside the
Ground Control Station. This technology will be added as one of many layers of safety for applications
to conduct UAS BVLOS operations. The radar operates in the S frequency band. ADS-B and Mode C
sensor packages are receive only.

Table 1 lists the equipment specifications and table 2 shows the location data.
