BUS, CRS, High-Gain Antenna, ISS, IRIS, LECP, LEMPA, MAG, Optical Calibration Target, PPS, PLS, PRA, PWS, RTG and UVS…What do these acronyms stand for? Every week (from now till November) I’ll post some components that are part of the Voyager. So stay tuned and let’s get started with High-Gain Antenna and ISS. Continue reading…
The HGA transmits data to Earth on two frequency channels.
Imaging Science Subsystem (ISS)
The ISS is a modified version of the slow scan vidicon camera designs that were used in the earlier Mariner flights.
- Observe and characterize the circulation of the planetary atmosphere,provide limits on atmospheric composition, and determine the wind velocities in the regions observed.
- Obtain global multi-spectral coverage of all satellites; establish rotation rates and spin axis orientations.
- study the surface morphology of Triton at spatial resolutions less than 2 km.
- search for undiscovered satellites.
