Project Space Track began its history of satellite tracking from 1957–1961. Early Space Track observations of satellites were collected at more than 150 individual sites, including radar stations, Baker–Nunn cameras, telescopes, radio receivers, and by citizens participating in the Operation Moonwatch program. Individuals at these Moonwatch ...

As of February 20, 2010, three different NASA networks are used - the Deep Space Network (DSN), the Near Earth Network (NEN) and the Space Network/Tracking and Data Relay Satellite System (TDRSS). The DSN, as the name implies, tracks probes in deep space (more than 10,000 miles (16,000 km) from Earth), while NEN and TDRSS are used to ...
Apollo 7 slow-scan TV, transmitted by the RCA command module TV camera. NASA decided on initial specifications for TV on the Apollo command module (CM) in 1962. [2] [ Note 1] Both analog and digital transmission techniques were studied, but the early digital systems still used more bandwidth than an analog approach: 20 MHz for the digital system, compared to 500 kHz for the analog system.

The discovery and tracking of space debris is a growing problem. Among the 20–30 thousand large objects in orbit that are tracked, an estimated 100 million objects some as small as paint flecks are harder to track than the larger objects, but large enough to shield against if they collide with a space asset.

A simple single-arm barn door tracker can be made by attaching two pieces of wood together with a hinge. A camera is mounted on the top board, usually with some sort of ball joint to allow the camera to be pointed in any direction. The hinge is aligned with a celestial pole and the boards are then driven apart (or together) at a constant rate ...
