A Federal Register notice has announced Department of Transportation (DoT) plans to conduct additional testing of GPS/GNSS receivers this month as part of  their Adjacent Band Compatibility (ABC) Study. The notice was issued by DoT Assistant Secretary for Research and Technology Gregory Winfree.

The GPS Directorate is requesting public comments on proposed changes to several interface specification (IS) and Interface Control documents (ICDs) for GPS signals in space. GPS receiver designers will be particularly interested in the changes as they affect how GPS signals should be processed in user equipment. (more)  

Carnegie Mellon University (CMU) used visual, inertial and LiDAR sensors to create a surveying instrument that could eventually be used to model collapsed caves on the Moon, Mars and beyond. The CMU instrument applies geo-referencing technology, including KVH inertial sensors, to create high resolution 3D modeling of planetary caves. Precision mobile mapping will be critical to finding these caves, potential sites for extra-planetary colonies as well as environments for extra-terrestrial life.
When we're using a mobile location-based application such as getting driving directions from Google Maps, it's not surprising to see advertisements from local businesses showing up in our browsers. Customized advertising, after all, is Google's bread and butter. (more)
