Introduction
The expanding interest in medium Earth orbit (MEO) creates new commercial opportunities, yet most existing platforms are built for low Earth orbit (LEO) and are not suited to the extended mission durations and increased radiation levels found in MEO.
Technical contrast between LEO and MEO
LEO satellites typically operate between 200 and 2,000 km altitude, whereas MEO assets reside from 2,000 up to 35,786 km. This altitude gap introduces distinct thermal, mechanical and radiation stresses that can drastically shorten component life if not properly addressed.
Economic implications
Operators planning MEO constellations face considerably higher development and maintenance expenses. Parts designed for LEO often need costly upgrades or complete redesigns to survive the longer operational cycles in MEO.
Impact on the emerging orbital economy
The mismatch between current LEO technology and MEO requirements may slow the rollout of services such as global broadband, navigation and Earth‑observation, unless dedicated solutions are delivered.
Future directions
- Development of radiation‑hardening materials
- Improved power and thermal management systems
- Long‑term collaborations between industry and space agencies
