Abstract
A navigation, take-off, and landing support system (NTLS) that facilitates vertical landing at a landing area by an aerial vehicle comprises a plurality of pseudolites distributed proximate the landing area. Each pseudolite is configured to transmit a radio frequency (RF) signal that facilitates determining, by the aerial vehicle, its position and velocity relative to the pseudolite and whether the pseudolite is operating within a nominal operating range. A monitoring receiver is positioned proximate the landing area and is configured to receive RF signals from the pseudolites. A control system is in communication with the pseudolites and the monitoring receiver. The control system is configured to determine, based on the RF signals received from the monitoring receiver, whether the pseudolites are operating within a nominal operating range and to indicate to each of the pseudolites whether the pseudolite is operating within a nominal operating range.
