A bit like the RTAF's helicopters and transport planes then...?

to help in forest fire prevention and fighting

So does it have gallons of water on board, and face recognition, like on the BMWs, to identify the offending farmers?

Some more details about this satellite.

 

Firstly, Thais didn't build it.  It was purchased from a company based in the Netherlands.  It's a 6U size Cubesat, which will be placed into a low earth orbit (LEO), and will fall out of the sky after no more than about 5 years, (due to the pull of Earth's gravity).

 

Since it will be in a LEO (500 Km), this means that it will not appear stationary in the sky above Thailand, because the Earth is spinning.  It will appear to continually move across the sky from almost any location on Earth that it's viewed from.

 

Since the satellite doesn't appear stationary in the sky above Thailand, it will actually only be 'visible' for a couple of times each day, taking about 20 minutes to transit across the sky.  It's in this time-frame that the satellite camera can send photos back to the ground station in Thailand, (those could be real-time photos of Thailand, or stored photos that were taken when the satellite passed over another region of the Earth).

 

In another paper, the Thai military claim that this satellite would primarily be used to observe and survey Thai air space for defence and national security purposes, as well as detecting hotspots to prevent bushfires and water resources to combat floods or drought. In this way, the satellite cameras will play a crucial role in the RTAF's defence system, strengthening national security and preventing threats.

 

Hmm, all these goals can be achieved when there are only 2 or 3 daily passes over Thailand, each with a 20 minute viewing window?

 

There's absolutely nothing wrong with launching this kind of satellite to further one's knowledge of space technology, remote monitoring etc.  But please don't dress this little Cubesat up as something that it isn't 🙂

 

On low earth orbit LEO, Cans i hope. Just like the Crew here on Earth then

Total waste of the countries money. There are plenty of satellites around that can give aerial info over Thailand.  Presume it will crash !

its  running windows 95 (pirated)🤣

Thought they were supposed to save money not spend it like a drunken sailor. Sorry wrong branch. lol

 

It will be comforting to know they they now can track you without need for a QR symbol.

ah ha!! The home of "The Beatles" (famous UK pop group):-

 

In the town where I was born
Lived a man who sailed to sea
And he told us of his life
In the land of submarines
So we sailed up to the sun
'Til we found a sea of green
And we lived beneath the waves
In our yellow submarine

Interesting to note the Dutch contractor for the satellite!

Quote from Space.skyrocket.de:-

 

NAPA 1 or RTAF-SAT 1 (Royal Thai Air Force Satellite) is an earth observation nanosatellite built for the Royal Thai Air Force.

The Royal Thai Air Force contracted in July 2018 with ISIS of Netherlands for the delivery of an earth observation 6U CubeSat in orbit.

Indeed, although to be fair, all LEO satellites will re-enter the earth's atmosphere at some point, unless they have small rocket thrusters on board that are regularly used to maintain the satellite in correct orbit (such as on the International Space Station).

 

As to what the payload is, there are 2 cameras on board: "The main payload is a Gecko Imager, from the South African company SCS, capable of imaging in the RGB-band with an approximately 39m ground sampling distance from the typical Low Earth Orbit. There is also a secondary payload, which is a demonstration model of the TriScape 100 Imager from developer Simera Sense, with a target ground sampling distance down to 5m from the typical Low Earth Orbit."

Gecko Imager - only 23,000 euros my boy....

They have plans to bring this one back safely...
