Deleting raw GPS data from the mobile device

[supriya]

Hi

I am developing an GPS application which implements hot fix, warm fix and cold fix. am done with the hot fix. How to implement warm and cold fix?
To implement warm and cold fix, i need to delete almanac and ephemeris data (data retrieved from satellites) stored in the device. So where does the almanac and ephemeris data gets stored in the device?


Please help.

Thanks
