A test loop translator ( TLT) is a type of radio frequency converter or heterodyne, used to translate between uplink and downlink segments (generally in the same band), to allow for "loop-back" testing and calibration of a satellite ground station without the need to interface with the satellite. [1] [2] The test loop translator is an extremely ...
Inertial navigation is a self-contained navigation technique in which measurements provided by accelerometers and gyroscopes are used to track the position and orientation of an object relative to a known starting point, orientation and velocity. Inertial measurement units (IMUs) typically contain three orthogonal rate-gyroscopes and three ...
Ground station. A ground station, Earth station, or Earth terminal is a terrestrial radio station designed for extraplanetary telecommunication with spacecraft (constituting part of the ground segment of the spacecraft system), or reception of radio waves from astronomical radio sources. Ground stations may be located either on the surface of ...
SEA Underground. The SEA Underground, formerly called the Satellite Transit System ( STS ), is an automated people mover (APM) system operating in the Seattle–Tacoma International Airport in SeaTac, Washington, United States. Originally opening in 1973, the SEA Underground is one of the oldest airport people mover systems in the world.

test, she is judged not to have received a good education from the school. If the school does not make Adequate Yearly Progress (AYP) on student test scores, the school is considered not providing a good education to its students and is labeled ‘in need of improvement.’ The school then faces serious
Schuler tuning. Schuler tuning is a design principle for inertial navigation systems that accounts for the curvature of the Earth. An inertial navigation system, used in submarines, ships, aircraft, and other vehicles to keep track of position, determines directions with respect to three axes pointing "north", "east", and "down".
