Google provide raw GNSS measurements


Recommended Posts

Raw GNSS measurements from Android phones. Yep, they are coming. At Google we have been working with our GNSS partners to give application developers access to raw GNSS measurements from a phone.

This is really exciting, and marks a new era for our GNSS community. At Google I/O in May, we announced that raw GNSS measurements are available to apps in the Android N operating system, which will be released later this year. This means you can get pseudoranges, Dopplers and carrier phase from a phone or tablet.

When can you get it? Well, it will take some time to proliferate throughout the ecosystem, but the first phone that will provide raw measurements will be the Nexus phone that we will launch later this year, and then next year you will see new Android handsets start to support it, as it will become a mandatory feature in Android.

At the Institute of Navigation’s ION-GNSS+ conference this September, Frank van Diggelen and I will teach a tutorial where you can learn to access and use these raw measurements. This will be a hands-on course where you collect, view and process raw measurements. You will leave the class with the data, Google software tools, and the knowledge of how to use them.

This tutorial is open only to ION-GNSS+ attendees. To register for the conference, visitwww.ion.org/gnss/registration.cfm.
