Raw GNSS Data Recordings Inside and Outside of a Greenhouse

Three raw (i.e., In-Phase and Quadrature data with a software radio, and observation files) GNSS dataset were recorded using a LabSat Version 3 inside of the West Virginia University greenhouse and two outside recordings were also made to provide a quality reference and comparison. The outdoor location had to be an ideal location for satellite signal reception and the indoor location was a greenhouse room where satellite visibility was limited, susceptible to attenuation, occlusion and multipath. These recordings are all static and were made using a LabSat V3, a multi-constellation GNSS simulator that allows recording and replaying real GPS/GNSS signals. The antenna used for this is a L1 patch GPS/GNSS antenna. These recordings were made at a time of the day (Noon) such that it was consistent and comparable for all data sets, they are approximately 1.5 hours long. In addition to the raw recordings, RINEX observation files after processing with the GNSS-SDR software and playing the data into a Novatel OEM-638 receiver are included for each data set. Post processed position solutions obtained with the open-source RTKLIB library are also included for reference. This research was supported in part by USDA NIFA Project: 2017-67022-25926.
