Assisted GPS server
HTTP server that fetches the lastest available GPS ephemeris data from NASA / CDDIS and makes it available in JSON.
The data is fetched from NASA every 5 minutes. Make sure you run a cache in front of this server to avoid melting it (cache expiration is set to 5 minutes as well).
npm install
node agps.js
A compact gzipped JSON format is returned if the accept header is set to "application/json", otherwise a human readable HTML format is sent back.
