This system is operated by Nakajima Laboratory and Cho Laboratory in Tokai University, collaborated with research institutes such as Japan Aerospace Exploration Agency（JAXA).
There are three sites below;
- Shibuya, Tokyo [Tokyo campus (Shibuya), Tokai University] – Model 1
- Iriomote Island, Okinawa [Okinawa Regional Research Center (ORRC), Tokai University] – Model 1
- Kumamoto [Tokai University Space Information Center (TSIC)] – Model 2
TACPAS has Model 1 and Model 2, which were developed by Tokai University (2006) and by JAXA (2011) respectively.
Model 1 : a commercial digital camera, a fish-eye lense, a personal computer and some softwares
Model 2 : a commercial digital camera, a fish-eye lense, Linux board, some softwares and a GPS receiver
Model 2 : a commercial digital camera, a fish-eye lense, Linux board, some softwares and a GPS receiver
The photo is taken every 5 minutes and the system is designed to operate fully automatically.
