Summary
The FLOCK 1B-28 satellite, also known as Flock 1b-28, has a NORAD catalog ID of 40423 and an OBJECT_ID of 1998-067FP. It is a CubeSat (3U) configuration manufactured by PLABS in the US for technology purposes. Launched on November 20, 1998, from the TYMSC site using an Antares 120 launch vehicle from Pad 0A, it has dimensions of 0.3 meters in length and diameter with a span of 0.3 meters. Its dry mass is 4.5 kg, equal to its launch mass. The satellite features solar cells and batteries for power generation and carries either PS0, PS1 or PS2 imaging payload as part of the Dove 081B mission equipment. It has no motor propulsion except in cases like #Flock-3p', which uses FEEP technology. The satellite's shape is described as "Box+2 pan" with a reflectivity (RCS) of 0.097 m^2. Its expected lifetime varies from about one year for an ISS orbit to between two and three years in Sun-Synchronous Orbit (SSO).
