Abstract
Background: The deployment of Low Earth Orbit (LEO) mega-constellations (e.g., Starlink, OneWeb, Pulsar, IRIS) has driven interest in LEO-based Positioning, Navigation, and Timing (PNT) solutions [1], either through dedicated payloads or signals-of-opportunity.
Objectives: This work proposes a CubeSat mission aimed at verifying integrated LEO communication and positioning capabilities over Taiwan.
Methodology & Mission Plan:
- Constellation: One to four CubeSats will be deployed. Real-time positioning will be tested during simultaneous four-satellite visibility over Taiwan, while recorded-signal positioning will be used for partial constellations.
- Experiments: Dual-mode testing includes concurrent communication and positioning experiments, alongside communication-signal-based positioning.
- Orbit & Timing: Onboard position and timing will be synchronized via external GNSS services to support custom positioning signal broadcasts.
RF Specifications: Communication experiments utilize the K/Ka bands, while positioning signals operate across the L, S, and Ka bands.
