Access to comprehensive mapping data is a powerful tool for developers of online web-based and mobile apps who can now use Transas’ top-notch technology to build their own applications.
The Isat Data Pro(IDP) series operates on the Inmarsat I-4 constellation which provides improved network speed.
Polling request and response times now takes 30-45 seconds, which Transas says is four times faster than its predecessor.
The key to this new updating service is Jeppesen's distribution format, called C-MAP CM-93/3 and type approved by DNV.
This format can compress large amounts of navigational data to a size that makes online transmission rapid and reliable.
