ASAPS HARDWARE SYSTEM
PEMDAS has developed one of the world’s most reliable and accurate airborne weather sensor systems, the Atmospheric Sensing & Prediction System (ASAPS).
The PEMDAS developed Atmospheric Sensing and Prediction System (ASAPS®) is an airborne sensor designed to collect real-time (in situ) atmospheric data for generation of adverse weather warnings. Originally designed for and proven by the U.S. military’s Unmanned Aerial Systems (UAS), PEMDAS ASAPS has been enhanced to operate on commercial drones as well as general aviation aircraft such as the Beech King Air.
ASAPS collects and processes real-time atmospheric data into the PEMDAS NOWCasting system for two primary purposes:
- Provide early warning to aircraft operators of impending inflight weather threats such as icing and clouds.
- Generating real-time, high fidelity weather products such as icing and cloud layers, wind profiles and cloud-free line-of-sight views. This allows for improved flight planning, in-flight maneuvering and intelligent decision tools such as real-time navigational re-routing.
Case-in-point: In 2017, the ASAPS sensor supported aerial surveys of the Feather River downstream of the Oroville Dam in Northern California when heavy rainfall and erosion led to concerns the dam would fail and the entire lake would flood the river valley.
The PEMDAS Atmospheric Sensing and Prediction System (ASAPS) was critical to aerial surveillance of the damage, the assessment and initiation of repairs of the dam, and coordinating the evacuation of nearly 180,000 people living downstream. The ASAPS system was used to predict poor environmental conditions for airborne assets, helping ensure that Electro-Optical and Infrared sensors were not damaged by icing or other adverse weather conditions.
