Foreground: Jeff Graham (JSC, Titan, EVA Robotic Assistant Team) pauses at an extra-vehicular activity (EVA) traverse waypoint near the MDRS HAB while wearing the EVA Informatics Pack (InfoPak). The InfoPak is an optional add-on module for space suits and includes differential GPS equipment and a PC-104 computer connected to an enhanced 802.11B wireless network. During MDRS16, Jeff and the ERA team are using the InfoPak to simulate informatics operations during suited EVA in preparation for suited Mobile Agents experiment scenarios.

Background: NREN Transportable Earth Station (TES) satellite equipment is shown in the operational deployed configuration. TES is one element of an end-to-end Space Network Emulator that is capable of including realistic interplanetary communications delay. TES is using a commercial Ku-band satellite and a ground station at Glenn Research Center to provide an asymmetric communication link at the MDRS site of approximately 6.5 megabits per second into the site, and 4.5 megabits per second out of the site. These link rates simulate expected optical deep-space communications rates within Earth's Neighborhood a decade in the future. (Photo and caption provided by Marc Seibert)

Jeff Graham (JSC EVA Robotic Assistant Team) pauses at the differential GPS (DGPS) reference station during a simulated extra-vehicular activity (EVA) traverse. The DGPS reference station is installed approximately 11 meters above the MDRS HAB facility to increase the operational range of the station. During MDRS16, Mobile Agents nodes use the reference station to correct navigational accuracy in real-time to within 2 centimeters of absolute position. Jeff is wearing the EVA Informatics Pack (InfoPak) on his back to mark EVA waypoints in preparation for Mobile Agents scenario run later in the day. The InfoPak is an optional add-on module for space suits that includes a DGPS receiver and a PC-104 computer connected to an enhanced 802.11B wireless network.
