(3) Command receipt (from the SCU), processing, storage (if a delayed command), and transfer to the instruments. (4) Time/attitude synchronization with the spacecraftÕs Attitude Determination and Control system for generation of the nadir and sun pulse signals sent to the instruments. (5) Deckplate thermal control. (6) Additional EEPROM storage for instrument software or tables. (7) Power switching and current limiting. The SCU provides the following major functions for the Observatory: (1) Ground command receipt, processing, storage (for delayed command execution) and relay to the CIDP. (2) Telemetry data formatting and downlink (3) Spacecraft attitude determination and control. (4) Spacecraft thermal control. (5) Spacecraft power management. (6) Spacecraft housekeeping data acquisition, formatting, and storage. (7) Management of the Mass Memory Module. (8) Management of the engineering and high speed telemetry downlink.

Stop:2005-12-18 23:59:59 Instrument:Low-Energy Neutral Atom Imager (LENA) Resource:NumericalData
This is a set of data at multiple processing levels from all IMAGE instruments. Built by a UNIX-afficionado requiring editing .cshrc's, etc., the data are in Universal Data Format (UDF), and at the moment, has no PC install documentation. UDF software is available to read the IMAGE UDF files.

3) MMS 1 Active Spacecraft Potential Control, Sensors 1 and 2 (ASPOC) Level 2, Quick-Look Survey maxmize

Stop:2016-09-14 07:59:55 Instrument:MMS 1 Active Spacecraft Potential Control (ASPOC) Instrument Resource:NumericalData
MMS 1 Active Spacecraft Potential Control (ASPOC) - Sensors 1 and 2 Ion Beam Current Rates, Beam Energies, and Instrument Status variables. In tenuous plasma regions, the floating potential of a sunlit spacecraft is positively charged, reaching up to tens of Volts. The corresponding electric field disturbs the ambient plasma measurements obtained from electron and ion sensors and the large fluxes of attracted photo-electrons can significantly reduce the lifetime of the micro-channel plate. The electric field measurements can be also contaminated by the high spacecraft potential values. The Active Spacecraft Potential Control neutralizes the spacecraft potential by releasing positively charged Indium ions. The ASPOCs neutralize the electrical potential of the spacecraft, limiting or eliminating spurious electric fields that can contaminate measurements. This allows observations of the more scientifically important low-energy ions and electrons.

A directory containing daily ftp-downloadable files containing readout-by-readout listings of HET housekeeping paramaters (Voltages, Temperatures, Offsets). The naming convention of the files is uly_het_full_house_YYYDDD.txt, where YYY indicates the three-digit year since 1900 (e.g. YYY=090 for 1990, and YYY=102 for 2002) and DDD indicates the three digit day of year (Jan. 1 = 1). In each file, following a detailed description of the format, the data consist of a a listing of HET housekeeping parameters measured at the time listed in the first 4 columns of each line. Each line contains data for one readout of the parameters. The first 4 columns give the time of the measurement as fractional year (to 12 decimal places) and as year since 1900, day of year, and ms of day. At the most common science telemetry rate, 2048 bps, each parameter in this file is read out once every 256 seconds. The measurements are instantaneous, and do not represent an average of values over the interval since the last readout. The sole function of these parameters is to monitor instrument health. No noise-removal or despiking has been done, so caution must be used in interpreting isolated large increases or decreases in the measured parameters.
