BARREL Level 2 Ephemeris 4-s Data from 2013 and 2014 Launches

ResourceID
spase://NASA/NumericalData/BARREL/EPH/L2/EPHM/PT4S

Description
This data group contains ephemeris data (Lat, Long, Alt, and Time) from multiple balloons of the BARREL (Balloon Array for Radiation-belt Relativistic Electron Losses) investigation in 2013 and 2014. Data include geographic and magnetic coordinates. Geographic coordinates are obtained from onboard GPS unit; magnegic coordinates are derived using the IRBEM FORTRAN library for Kp=2 and Kp=6. Data products are each returned from the payload once every 4s.

Caveats
Known hardware and calibration issues are: Payload 1L - Lost contact on ascent, returned no science data; Payload 1N - GPS failure early in flight => location and timing errors exist; Paylaod 1W - balloon failed on launch, returned no science data.
