Figure 6-102. Workstation COP layout. Side-by-side TVW application windows above, with separate feeds from SEAAR2u and SEAAR2u radars at SEA in each window; Google Earth window below, with both live radar feeds presented in a single integrated display (i.e., COP). SEAAR1m is a mobile radar on the ground at SEA that was not used in this demonstration. 230
Results Table 6-32 records the timestamps and calculated latencies from the twelve screen captures. Table 6-32. Latency of live radar feeds from the SEAAR2u and SEAAR2l radars at SEA streamed to separate instances of the TVW application and to a single instance of the COP visualization tool, Google Earth (GE).

The latencies in the Google Earth (GE) timestamps ranged from 5-9 seconds, with an overall mean latency of 7 seconds. We attribute the higher latencies in the Google Earth timestamps to the (default) refresh rate of 2.5 seconds that was specified in the kml 24 file we used for retrieving target information from the RDS. This setting meant that if new target information was available, it would not be retrieved for at least 2.5 seconds. Conclusion We successfully demonstrated Performance Criterion SD2.1 by establishing that the latencies of target track data streamed across the internet in real time from two radars and integrated into a common operational picture 3300 km away were 10 seconds or less. The ability to integrate track data from multiple radars into a single display (i.e., a COP) will provide air operations and natural resources management personnel better situational awareness of bird activity at their facilities. The COP display will provide increased coverage of the facility and beyond and the overlapping coverage by the radars will result in potentially fewer “blind spots”. 07 24 KML is the file format developed by Google for displaying geographic data in an Earth browser such as Google Earth. 231
