To monitor the whole Shanghai Expo Park, a vehicle tethered aerostat optoelectronic monitoring platform with the
characteristic of time-sensitive and all-weather monitoring is described in detail in this paper, which is hung beneath the
tethered balloon and equipped with a variety of payloads, including visible light monitoring system, infrared monitoring
system, hyperspectral monitoring system, GPS/INS system, monitoring and control system and so on. These equipments
can be used for real-time monitoring, environmental monitoring, and ground target location of Shanghai Expo Park. The
output High Definition (HD) image of Shanghai Expo Park from visible light monitoring system is clear and stable, and
the stabilization accuracy of visual axis is 0.07°(3δ). The optoelectronic monitoring platform system uses the target
location technology based on Global Position System/Inertial Navigation System (GPS/INS) system to output real-time
location data compatible with Geographic Information System (GIS). Test results show that the maximum errors
between the location results (latitude and longitude) solved by the target location program and the reference target are
0.2 0/00(latitude) and 2 0/00(longitude). Now the whole system has been used for surveillance the Shanghai Expo Park since
April 2010.
