E-2 Phase 2 Project Goals
Phase 2's primary goals are:
- To be capable of maneuvering on the surface and at depths up to 30m.
- To navigate autonomously from a shore launch site to a predesignated zone of interest at least 50km from the launch point.
- To remain on station, within a 500m radius, with a fixed error factor determined by active GPS Selective Availability features in the target area during the mission.
- To operate without physical intervention or assistance for 365 consecutive days with an average uptime ratio of approximately 33% (120 uptime days). An uptime day is defined as any period from 00:00 to 23:59, local time, during which the vehicle spends at least six consecutive hours submerged to a depth of at least 10m.
- To return daily GPS position data, at minimum, to a shore monitoring station via a satellite telemetry channel.
- To achieve all primary goals within a cost budget of US$25,000 for bill-of-materials, engineering, tools and testing, plus a further $2,000 for ongoing expenses (e.g. satellite communications fees).
A secondary goal is for the vehicle to navigate back to the launch point for recovery after the mission is complete. However, recovery is not an essential goal; vehicle loss after completing primary goals is acceptable.
