Unmanned aircraft systems (UASs) and related techniques are provided to improve the operation of unmanned mobile sensor or survey platforms. A flight altitude estimation system includes a logic device configured to communicate with a communication module and a flight barometer coupled to an unmanned aerial vehicle (UAV), wherein the communication module is configured to establish a communication link with a base station associated with the mobile platform, and the flight barometer is configured to provide flight pressures associated with the UAV as it maneuvers within a survey area. The logic device is configured to receive demark pressure data from a demark barometer coupled to the base station and determine a differential flight altitude estimation based, at least in part, on received flight pressure data and demark pressure data, a reference flight pressure and a reference demark pressure corresponding to a flight initiation location of the base station.
