Claim 8:
9. An altitude initialization and monitoring system (AIMS) for initializing and monitoring and the altitude output of an Airborne Wireless Sensor System (AWSS), the AWSS associated with an unmanned aircraft system (UAS) and operative to communicate altitude and other Remote Identification (RID) data (RIDD) to end users, the RIDD being displayed on a remote receiver/display device (RRDD), the system comprising:
an AWSS associated with a UAS, the AWSS having,
one or more sensor modules configured for sensing UAS navigational flight data, the sensor modules including at least a primary pressure altitude sensor,
one or more communication modules for communicating data between the RRDD and the AWSS,
a non-volatile memory (NVM) for storing first computer software instructions and altitude initialization data,
a processor module, configured to interface with the one or more sensor modules, the NVM, and the one or more communication modules, the processor module further configured to execute the first computer software instructions stored in the non-volatile memory, the execution of which:
initializes the AWSS prior to flight while the UAS is on or near the ground, the initialization including at least the step of reading the altitude initialization parameters and determining a pressure altitude correction factor;
stores the initialization parameters and correction factor into AWSS NVM;
senses, raw UAS pressure altitude while the UAS is in-flight by periodically sampling the primary pressure altitude sensor;
processes the sensed raw UAS pressure altitude with the processor, the processing comprising at least the step of determining a corrected UAS pressure altitude by applying the correction factor to the raw sensed pressure altitude;
transmits to the RRDD, the corrected UAS pressure altitude,
receives from the RRDD a reset command, and
executes a re-initialization of the UAS altitude based on the received reset command, the re-initialization comprising at least re-reading the altitude initialization parameters and re-determining a pressure altitude correction factor.
