Two Polar Relay Scanners with Carrier

The paired, packaged and ready to mate Polar Relay Scanner bundle. The base carrier provides 2,400dV for target body capture burn and in some cases the injection burn as well. The base carrier uses an enhanced probe core compared to the Relay’s probe for better autonomous targeting. The carrier itself is normally deorbited after satellite deployment and carries two short range antennas to control its terminal burn.

Depending on the target body and launch windows, the carrier might be fully used as the injector from Kerbin if the resulting orbital adjustments and capture can be accomplished by the individual fuel tanks of the Relays. When used as such, a collision injection burn is preformed before relay deployment and then the relays adjust away from the interception. This provides fire-and-forget deorbiting months or even years before the capture burns need to be orchestrated. However, with two relays to capture, you need to make sure one arrives later than the other to preform each capture burn. This was used to send one relay to Duna and another to Ike with the carrier impacting with Ike.

The Polar Relay Scanners fit just inside the limits of the 2.5m fairing. This limits sat. deployment to a certain order. The lower inner sat. isn’t included in the normal action group 2 for deploying solar panels or its regular antenna, as the truss structure is in the way. The inner sat. is deployed first and the carrier rotates out of the way. The freed relay can then deploy its array with 3 and adjusts its orbit to the final inclination. The outer relay is then free to wait for the first sat. to stabilize its polar orbit so it can match, using some of the carriers fuel before deploying itself. This leaves the second relay with more fuel to adjust its orbit to mirror the firsts exactly.

For the equivalent package with the newer RA-100 equipped Polar Relay Lite, see the Jool MIRV Round. That model incorporates a disintegrating truss structure and has a much more… explosive deployment phase that solves the truss problems with the original package.

For a more powerful, long distance package see the Relay Power Flower Scanner Package for 16 RA-100 dishes per relay.

Fairing settings: 2-sided clamshell deploy, max ejection force by default.

Built with 53 of the finest parts, its root part is science.module.

Built in the VAB in KSP version 1.2.2.
