SWOT Satellite Reconstructed Attitude Data

공공데이터포털

Satellite attitude reconstructed from combination of onboard gyro and star tracker data. Daily 26-hour files centered at 12:00:00 (TAI) provide quaternions to represent the rotation between the spacecraft body-fixed KaRIn Metering Structure Reference Frame and the inertial Geocentric Celestial Reference Frame. Available in netCDF-4 file format with latency of < 1.5 days.

PM1 5-min Spacecraft attitude data from GBAD - NRT

공공데이터포털

PM1ATTNR is the Aqua Near Real Time (NRT) daily spacecraft attitude data file in native format. This is MODIS Ancillary Data. The data collection consists of PM1 Platform Attitude Data that has been preprocessed by ECS to an internal standard supported by the ECS SDP Toolkit. This data is typically used in determining the geolocation of earth remote sensing observations.The file name format is the following:PM1ATTNR_NRT.Ayyyyddd.hhmm.vvv where from left to right: PM1 = PM1 (Aqua); ATT = spacecraft attitude; N = Native format; R = Refined; A = Acquisition; yyyy = data year, ddd = Julian data day, hh = data hour, mm = data minute; vvv = Version ID.

Ground-Based Global Navigation Satellite System (GNSS) GPS real-time POD Attitude Quaternions (30-second sampling, 60-second files) from NASA CDDIS

공공데이터포털

This product contains a time series of attitude quaternion components for healthy satellites in the GPS constellation that are accumulated every minute throughout the day. The product is generated at JPL's Global Differential GPS Operations Centers in real-time. The data in this product can be concatenated with other daily products to provide larger coverage in time.

SWOT Level 1 Onboard Tracking Data from Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS)

공공데이터포털

Tracking data measurements from the Doppler Orbitography and Radiopositioning Integrated by Satellite (DORIS) payload receiver onboard SWOT. The tracking data are generated using signals from DORIS ground beacons and are used to perform precise orbit determination of the SWOT spacecraft. They are also used to compute the precise orbit ephemeris(POE), and the medium-accuracy orbit ephemeris (MOE) used for SWOT data processing. Distributed as one file per day in RINEX file format, available with latency of < 2 days.

SWOT Level 1 Onboard Tracking Data from Global Positioning System Payload (GPSP)

공공데이터포털

GPS tracking data measurements from the GPS Payload (GPSP) receiver onboard SWOT. The tracking data are generated by the GPSP using signals from the GPS constellation of satellites and are used to perform precise orbit determination of the SWOT spacecraft. They are also used to compute the precise orbit ephemeris (POE), and the medium-accuracy orbit ephemeris (MOE) used for SWOT data processing. Distributed as one RINEX file per data downlink regardless of temporal coverage, available with latency of < 2 days.

VG2 J/S/U/N/SS PWS RESAMP SPECTRUM ANALYZER HOUR AVG V1.0

공공데이터포털

This data set contains hourly RMS averages and peaks of calibrated electric field measurements taken by the spectrum analyzer component of the Plasma Wave System (PWS) onboard Voyager 2 for the entire mission. Most noise spikes were removed prior to processing in order to provide more reliable values. Each record contains the spacecraft event time at the beginning of the processed hour, 16 RMS electric field averages corresponding to the 16 frequency channels of the instrument ranging from 50 Hz to 10 kHz, and 16 maximum values in the same units for the same frequencies.
