ZA685 Rocket's Homing Navigation System

Electronic/radio-based navigation subsystem of the ZA685 rocket, separate from the propulsion system. Adapted by Zoe to lock onto Phipps' radio distress signal, enabling a tail-first landing on Moonbase despite the Ice Warriors' occupation. Operates independently of the propulsion system and is functional when the homing equipment is used, solving the crew's stranding problem.

Purpose

Locks onto Phipps' radio signal to navigate the rocket's high-risk tail-first landing on Moonbase

Significance

Provides the crew's only path to land on occupied Moonbase and halt the Ice Warriors' seed dispersal plan, heightening tension through dependence on a makeshift signal under enemy threat

Doctor risks landing despite Ice Warrior warning

The rocket's homing equipment is adapted by Zoe to lock onto Phipps' radio signal, providing the precise navigation needed for the tail-first landing. This improvisation is essential, as the rocket's standard navigation systems are inoperable due to the fuel shortage and the Ice Warrior occupation of Moonbase. The homing equipment's ability to sync with Phipps' transmitter transforms his distress signal into a critical tool for survival, guiding the team through the perilous descent. The Doctor secures the radio link, ensuring the signal remains strong enough for Zoe to calculate the trajectory accurately.

Before: Functional but not initially configured to receive Phipps' signal, requiring Zoe's technical adaptation.

After: Reconfigured and locked onto Phipps' transmitter, successfully guiding the rocket's descent.
