Dual-satellite lunar navigation system technology demonstration. |
| Description |
"The LunaCube is a dual-satellite lunar navigation system that employs the multi-epoch doubledifferenced pseudorange observation (MDPO) algorithm. The MDPO process involves collecting pseudorange measurements between two lunar orbiters and both the user and surface reference receivers. Through the double-difference observation process, the influences of satellite orbit determination (OD) errors and satellite clock offset on user positioning accuracy are significantly eliminated. This reduces the reliance on high-standard onboard clocks that require high power. Consequently, it enables the use of small-sized satellites, achieving a 50-meter user positioning accuracy with just a one-minute observation by placing two 6U satellites in a low lunar orbit (LLO)." |
