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

GBO Data Flow

THEMIS/GBO CDR Peer Review 7 Univ. of Calgary, Apr. 26-27, 2004

Data Responsibilities

Collaborator’s responsibilities:1) UCalgary physically installs and maintains the Canadian GBO's

2) UCB physically installs and maintains the Alaskan GBO's  

3) UCalgary recovers all GBO data (UCB ASI, UCLA GMAG, H&S) and GBO team (UCLA, UCB, UA) picks up data at UCalgary.

4) UAlberta recovers CGSM and NRCAN GMAG data. UCB picks up data from UAlberta.

5) UCalgary responds to all high level GBO H&S issues. UCB acts in backup capacity for this role.

6) UCalgary maintains the physical status of the Canadian GBO's

7) UCB maintains the physical status of the Alaskan GBO's

8) UCLA validates the GMAG data and directs UCalgary to make any configuration or calibration changes. Changes are discussed and approved by GBO team.

9) UCalgary validates ASI data. UCalgary will make changes to an instrument configuration/calibration after consulting with the GBO team (if the action is not already specified in the ops doc).  

10) UCLA will recover the E/PO data. UCB picks up data from UCLA.

11) UCLA will validate data and respond to any H&S issues.

CDR Peer Review Results

RFA # Status Title Action SummaryGBO-1 Closed Create test and verification

planA T/V Plan document is forthcoming. Test matrix and test flow are completed.

GBO-2 Closed Create configuration control plan

Each site will have hardware configuration list that is unique. Software configuration for each site will be identical, based on reference system developed and maintained at UCB. This will be covered in CC Plan.

GBO-3 Closed Provide go/no-go criteria on GBO operational components

The GBO Operations Handbook will cover this.

GBO-4 Closed Specify mission criticality of E/PO elements

E/PO sites have never been considered as mission critical elements. They are educational opportunities.

GBO-5 Closed Responsibilities for Critical Monitoring

GBO Operations Handbook will cover this.

GBO-6 Closed Establish network security plan GBO network security plan is in process. Will cover details of filtering network I/O, and configuration of network data servers.

GBO CDR Peer Review on 26-27 April, 2004 resulted in 6 RFAs. All have been closed by the review board.
