Yes, the UGRF network allows you to post-process your raw RINEX data efficiently. To do this:

• Log in to Your SBC Account: Access your Spider Business Center (SBC) account using your credentials. If you don’t have an account, you must register to access the post-processing tools.
• Navigate to the “Post Processing”: and select the "Computations" option.
• Upload Your RINEX Data: Prepare your raw RINEX files (supported versions include 2.11 and 3.3) and upload them through the computations interface.
• Processing with UGRF CORS Stations: The system will process your RINEX data using corrections and reference data from the UGRF CORS stations closest to your survey location.
• Receive a Detailed Report: After processing, the results will be presented to you in a detailed report, including corrected coordinates and relevant quality metrics.

The RINEX file interface uses UTC (Coordinated Universal Time) to align with global GNSS standards and ensure consistency in data usage across different time zones. This standardization is crucial for accurate processing and interpretation of GNSS data.

In Uganda, the local time is East Africa Time (EAT), which is UTC+3. This means that:

• If it is 3:00 PM EAT in Uganda, the corresponding time in UTC is 12:00 PM UTC.
• Similarly, a RINEX file generated at 6:00 AM UTC corresponds to 9:00 AM EAT in Uganda.

Understanding this relationship ensures you request the correct timeframe for your RINEX data, avoiding any mismatches or gaps in the datasets critical for post-processing and analysis.

RINEX 2.11 and 3.03 formats are supported for online post-processing. By supporting these widely used RINEX formats, UGRF ensures compatibility with a broad range of GNSS applications.
