Deep-Learning-Based Tracing for Satellite Telemetry
2023The mechanical section of the telemetry data from the scientific satellite “Lomonosov”, (such as yaw, pitch, and roll angles of the spacecraft’s main axes, along with its programmed and measured velocities) is pre-processed (alignment, reflection, and binarization) and used for anomaly behavior propagation.

An integrity checking system for satellite telemetry
IEEE Pacific Rim Conference on Communications, Computers, and Signal Processing. Proceedings, 2002An integrity checking system (ICS) for satellite telemetry is described. The integrity of satellite telemetry is defined in terms of relevance, correctness, completeness, and confidence. The relevance factor provides the basis for partitioning the telemetry data set into relevant and irrelevant data for current processing needs.

Earth satellite telemetry coding system
Electrical Engineering, 1957The different bandwidth requirements for the various inputs from the transducers in the earth satellite led to a system which is a combination of time-sharing and frequency-sharing telemetry. To illustrate, a simple three-channel system is first described. This is then extended to cover the 48-channel system.

Lossless compression for archiving satellite telemetry data
2000 IEEE Aerospace Conference. Proceedings (Cat. No.00TH8484), 2002We present a method for lossless compression of satellite data for archiving. The method is of low complexity and has been demonstrated to work successfully on actual telemetry data.

Wireless Telecommand and Telemetry System for Satellite
2007 3rd International Conference on Recent Advances in Space Technologies, 2007The telecommand and telemetry (TC-TM) subsystems are a vital component of any spacecraft and requires an interconnection between all other subsystems, in addition to the RF link to the ground segment. Traditionally all these on-board data communication requirements have been met by some combination of IEEE-1553 or RS-232 links.

Telemetry from the First Chinese Artificial Earth Satellite
Nature, 1970THE first Chinese artificial Earth satellite was launched at approximately 1330 UT on April 24, 1970. The announcement of the launch, giving a transmission frequency of 20.009 MHz, was made in Peking at 1232 UT on April 25. First signals were received at Kettering Grammar School at 1402 UT, towards the end of the twelfth orbit of the Earth.

Satellite Telemetry: Performance of Animal-Tracking Systems
The Journal of Wildlife Management, 1991We used 10 Telonics ST-3 platform transmitter terminals (PTT's) configured for wolves and ungulates to examine the performance of the Argos satellite telemetry system. Under near-optimal conditions, 68 percentile errors for location qualities (NQ) 1, 2, and 3 were 1,188 903, and 361 m, respectively. Errors (r E ) exceeded expected values for NQ=2 and 3,

A simple meteorological buoy with satellite telemetry
Ocean Engineering, 1983Abstract A small, inexpensive, and easily deployable meteorological buoy is described. Buoy motion is greatly reduced by appropriate ballast techniques; vector averaging further removes buoy motion effects from wind data. Data is transmitted to the GOES satellite and is retrieved by telephone.

HARBOR SEAL TRACKING AND TELEMETRY BY SATELLITE
Marine Mammal Science, 1989AbstractWe tested a satellite Platform Transmitter Terminal (PTT) in the laboratory (on a float and on captive seals) and on a free‐ranging harbor seal in the Southern California Bight to investigate the utility of satellite telemetry in documenting seals’at‐sea behavior and movements.

Marbled Godwit migration characterized with satellite telemetry
The Condor, 2014ABSTRACT Marbled Godwits (Limosa fedoa) breed in 3 disparate areas: The majority breed in the prairies of midcontinental North America, but there are also 2 small and widely separated tundra-breeding populations, 1 in eastern Canada and 1 on the Alaska Peninsula, USA. The major winter ranges include the Atlantic, Pacific, and Gulf coasts of the USA and
