This Is How The Genius Elon Musk Will Give Free WiFi To The Entire Planet

Posted by in categories: Elon Musk, internet, satellites, sustainability

The very same guy, who invented PayPal, created the Tesla Cars, plans to create “SolarCities” and developed cars that will make money for you when you don’t use them, has ANOTHER brilliant idea. Elon Musk plans to launch 4,000 low-orbit satellites in order to give free internet access worldwide, two of them has already been launched a month ago.

Quantum ‘compass’ could allow navigation without relying on satellites

Posted by in categories: quantum physics, satellites

The UK’s first quantum accelerometer for navigation has been demonstrated by a team from Imperial College London and M Squared.

Most navigation today relies on a system (GNSS), such as GPS, which sends and receives signals from satellites orbiting the Earth. The is a self-contained system that does not rely on any external signals.

There’s a region over South America where NASA shuts down its satellites

Posted by in category: satellites

It’s called the South Atlantic Anomaly.

The closest radiation belt to Earth roams above South America. It is called the South Atlantic Anomaly and gives off high levels of radiation that has been known to destroy satellites.

Diwata-2 successfully launched to space, makes first contact

Posted by in categories: energy, satellites

Contact successful!

Diwata-2 was successfully launched to space on October 29, 2018 at 12:08 GMT+08 from the Tanegashima Space Center in Japan via H-IIA F40 rocket. It is one of the small satellites piggybacked with the main payloads IBUKI-2, also known as GOSAT-2 (JAXA’s Second Greenhouse Gases Observing Satellite), and KhalifaSat, a remote sensing Earth observation satellite developed by the Mohammed bin Rashid Space Centre (MBRSC) in the United Arab Emirates. The other small satellites are the Japanese-made Tenkou, PROITERES-2, Stars-AO, and AUTcube-2. Diwata-2 was inserted into the Sun-Synchronous Orbit at an altitude of 621 km, 43 minutes and 20 seconds after rocket lift-off.

On Oct 29, 2018 at 13:52 GMT+08, initial contact was established between Diwata-2 and the Ground Receiving Station (GRS) located at the Department of Science and Technology Advanced Science and Technology Institute (DOST-ASTI). Short telemetry data was received from the satellite on that day. Diwata-2 was initially tracked using pre-launch orbital parameters. As of 12:40 PM yesterday, October 31, 2018, the GRS can now read the satellite’s status, including vital signs such as fully charged batteries, normal power consumption, and good communication link. Commands were successfully sent and initial check procedures will continue throughout the first week from launch. Initial image captures from the cameras can be expected in the coming days.
