Navigating the Cosmos: Unveiling the Distinctions, Advantages, and Tomorrow’s Opportunities of LEO Satellites
NEWS
In the spotlight, ambitious LEO (Low Earth Orbit) satellite projects have garnered widespread attention. But what exactly are LEO satellites, and what significance do they hold in the wireless communication industry?
Orbiting 300 to 1,500 kilometers above, these artificial satellites stand out for lower latency, crucial in enhancing communication transmission. Vital for wireless industries, LEO satellites redefine connectivity with speed and efficiency.
Differences Between Satellite Types
Before delving into the specifics of LEO satellites, let’s first exploring satellite types by orbital altitude. These include High Earth Orbit (HEO), Geostationary (GEO), Medium Earth Orbit (MEO), and, the focus in this article, Low Earth Orbit (LEO) satellites.
| HEO | Altitudes exceeding 36,000 km | Technological development , observational activities |
| GEO | Altitude around 36,000 km, complete an orbit in precisely 24 hours, synchronizing with Earth’s rotational speed | TV broadcasting , broadcasting services |
| MEO | Altitude 5,000 to 20,000 km | GPS navigation , positioning |
| LEO | Altitude 500 to 1,200 km | Communication, remote sensing, navigation, meteorology, scientific exploration, and defense |
Technical Overview of LEO Satellites: Frequency Bands
Current frequency utilization involves two bands: Ku-band for user downlink (10.7-12.7 GHz) and Ka-band for user uplink (27.5-29.1 GHz and 14.0-14.5 GHz). Future plans to expand into Q/V-band, encompassing user/feeder downlink (37.5-42.5 GHz) and uplink (47.2-50.2 GHz, and 50.4-52.4 GHz).
The linchpin of satellite communication is attributed to its deployment of a communication payload. YTTEK’s Y.LOAD is a payload tailored for LEO satellites-ground communication. With a software-defined radio (SDR) architecture, Y.LOAD is highly flexible, perfect for diverse wireless communication needs in space.
Furthermore, YTTEK provides a comprehensive solution for LEO satellite communication. From the satellite payload to the array antenna at the ground station and the high-speed satellite modem, Y.FORCE S. Our end-to-end solution marks a pinnacle in the satellite sector, providing a seamless and advanced communication infrastructure.
YTTEK’s Vision for Future Applications of LEO Satellite
Due to their proximity to Earth, LEO satellites possess advantage such as low latency, high bandwidth, and cost-effectiveness. In areas where setting up ground stations is inconvenient, such as high mountains, the marine, remote regions, or on airplanes. Satellite networks can provide full-coverage signal connection,addressing the limitations of existing mobile communication networks.
The deployment of LEO satellites also makes the establishment of a global satellite network more feasible, bringing about significant technological breakthroughs in global communication, emergency response, and disaster rescue.
Unlocking a future of wireless communication that is both convenient and globally accessible, LEO satellites mark the beginning of a new era. YTTEK, at the forefront of innovation, paves the way for a connected world like never before.
