Here discloses an apparatus for evaluating the ground terminal antenna and simulating satellite orbital trajectory using at least one unmanned aerial vehicle configured to emulate satellite movement based on a pseudo satellite trajectory. Apparatus encompasses a base station for establishing telemetry with a ground terminal antenna and said at least one unmanned aerial vehicle on a flight path designed for a planned scenario of a satellite. The base station is configured to process the telemetry data and perform one or more measurements based on a set of operational angles and target direction of said at least one unmanned aerial vehicle on the flight in relation to providing the orbital trajectory simulation of the satellite with respect to the planned scenario. One or more measurements comprise an offset measurement based on the set of operational angles of the ground terminal antenna in relation to the target direction of said at least one unmanned aerial vehicle; and a tracking accuracy measurement based on the set of operational angles of the ground terminal antenna and target direction of said at least one unmanned aerial vehicle following the flight path for a time period.
