Ground Based Observatories (GBO) Program Schedule and Status Stewart Harris

1. Ground Based Observatories (GBO)Program Schedule and StatusStewart Harris

2. Approach to System I&T • Lab testing where necessary and possible • For instance, testing of temperature limits on cameras • Cold limit testing on commercial components • Get in the field early and often • Establish network of GBOs well before satellites launched • Prototype to be deployed winter ’03-’04 • ASI deployed with OSE in Calgary late Feb. • CSE deployed in Athabasca mid-Apr • GMAG (E/PO type) deployed in Athabasca mid-Apr • Original Deployment Schedule • 5 Units to be deployed by winter ’04-05 • Additional 15 Units deployed by winter ’05-06

3. Current Deployment Schedule • Deployments scheduled between May and Oct in ’04, ’05, ‘06 • By Winter ’04-’05: 6 GBOs done • Summer ’04: deploy 4 in Canada, 2 in Alaska • By Winter ’05-’06: 14 GBOs done • Summer ’05: deploy 6 in Canada, 2 in Alaska • Demonstrate operational breadth of network • By Time of Themis Launch (Oct. ’06): 20 GBOs completed • Summer ’06: deploy final 6 in Canada • Complete the network, have all operating

4. Schedule Summary Issues: 1) KAPU is missing a magnetometer 2) Magnetometer at Contwoyto Lake is ~140km from LGRA

5. Schedule Detail(‘04)

6. Status/Issues • GBO Production Procurement Status/Issues • ASI and OSE procurement is already in progress • Cameras, Lenses, Power components already in house • ASI Enclosure production is in procurement • Need to identify sites that require a Computer Enclosure • Ideally we purchase what we need in one order • Changes to design will likely cause some delay in fabrication • Open Issues • Enough magnetometers? • Computer selection • Sun shield design validation • Integration of Iridium is lagging • GMAG Linux software development and integration
