This article contains orbital elements but does not include an epoch, or date when those elements, which typically vary over time, were correct. Please help by adding the epoch for the current data, or changing the orbital elements to ones with a known epoch.
TopSat carries out imaging with a ground resolution of 2.5 m. Much smaller and cheaper than other imaging satellites of similar high resolution, TopSat has been used to demonstrate the feasibility of providing images on demand to portable ground stations, such as that which might be deployed by the military or another disaster relief organisation.
Payloads are separated by bullets ( · ), launches by pipes ( | ). Manned flights are indicated in bold text. Uncatalogued launch failures are listed in italics. Payloads deployed from other spacecraft are denoted in brackets.
