Satellite Sensor Gateway

Supervisors Terry Benzel, Young Cho, Wei Ye (Listed by Last name) Summary Satellite Sensor Gateway (SSG) project is originated to develop a turn-key solution to transmit field sensor data to the back-haul through satellite links. In the last year of the project, SSG has evolved for a more ambitious goal: to develop a turn-key solution for environmental sensing. We are trying to develop a system having the following features: Sophistication in Simplification: The system should be very easy to use for their end users – environmental scientists, who have little knowledge about computer science. Hardware Agnostic: Most current remote-sensing systems use customized, proprietary, and limited in function. Our system architecture is designed to break this limitation and tries to support as many sensors and communication devices as possible. Communication Standardization: We try to have our front-end system can communicate with back-end systems through multiple standard metadata languages. This feature enriches the compatibility to different existing back-end systems and simplifies the works to share data among different front-end systems. Fig-1 SSG System Overview As shown in Fig-1, our system can slightly separate into two parts: front-end system in the fields, and back-end system for end-users. Front-end system consists of one General-Purpose Processor (GPP) and sensors/sensor platforms attaching on the GPP. Currently our system supports following sensors/sensor platforms: CR10X, CR1000 by Campbell Scientific Inc., Compact RIO, and Vaisala Weather Station. For the back-end part, our system support Google Application Engine and Sensorbase. My involvement in this project is providing hardware support and implementation of the front-end system. I was responsible to develop the drivers for Campbell Datalogger CR10X and CR1000. These drivers will communicate with dataloggers, sending data sample back to upper layer or passing control command from upper layers. Fig-2 shows the software layers we implemented in our front-end system.
