Environmental Sensor for Autonomous UAVS

Improved observations of the battlespace are of key and growing importance in today’s combat environment. UAVs are making key contributions in this area, and sensor improvements are a key part of increasing UAV capabilities. However, all sensors are subject to degradation under detrimental environmental conditions. Adding a sensor system to UAVs that enables the real-time identification and assessment of such conditions will aid in the most effective use of UAVs and their onboard sensors as well as enable more accurate evaluation of the sensor data being returned. In Phase I, Anasphere built and tested two proof-of-concept UAV Environmental Sensor Systems optimized for use on small UAVs. These systems measure meteorological variables, plus precipitation rate and type, ambient light, and visibility. Power consumption is 400 milliwatts maximum, and the footprint is the same size as a credit card. Weight of the systems is approximately 3 ounces. On-board data processing allows other value-added parameters of significance to be computed and reported. In Phase II, these systems will be further developed and enhanced with wind measurement capabilities. Further prototypes will be iteratively developed, and the project will culminate in delivery and demonstration of production-form systems to the Army.
