Primal Space Systems (PSS) will prototype the GPEG.MIL (Geometry Pump Engine Group) protocol for efficient 3D geospatial data streaming over constrained tactical networks. The Phase I effort will demonstrate that the unique method of encoding and streaming this 3D data as visibility event (VE) packets could provide a >5x reduction in bandwidth requirements for streaming large urban canyon data sets. PSS will also demonstrate that the GPEG.MIL VE data stream will significantly improve the performance of 3D map-matching algorithms, enabling more rapid and precise (sub-meter) localization when matching to LiDAR data from low altitude unmanned aerial systems.This innovative approach eliminates a large amount of irrelevant, occluded data from the delivery stream as well as the downstream processing pipelines. The GPEG.MIL VE data stream will allow virtually instant, on-demand access to the relevant 3D geospatial data required for analysis, mission planning and precision GPS-denied navigation.For tactical visualization, the GPEG.MIL VE protocol will deliver virtually instant remote access to massive 3D geospatial data and support enhanced client-side rendering performance.For GPS-denied navigation, the GPEG.MIL data stream will deliver the data needed to enable more performant 3D map-matching algorithms supporting agile, intelligent autonomous operations deep into GPS-denied areas.
