Questions regarding Hourly updates of RINEX FIles
Posted: Sat Sep 10, 2022 4:05 am America/New_York
Hi,
We are using the CDDIS services for the testing of our GPS receivers for which we are using the hourly updates. We are attempting to download the data from Linux using the following command :
wget --no-check-certificate "ftps://gdc.cddis.eosdis.nasa.gov/gnss/data/hourly/$(date -u +%Y)/$(date -u +%j)/hour$(date -u +%j0.%g)n.gz"
We are using the data in order to generate the current ephehermerides & Almanac i.e., if my current UTC time is 13:00 hrs, I would want to generate for the current time. However, it is seen that the data is not available during several instances & it takes more than 1 hour from the website for the fresh data to be available.
Could you please let us know if there is any other detail that we are missing in order to get the current data ?
Regards,
ARK.
