  1. should this be completed on the blog or in our notebooks

  2. Yes. look at geosynchronous as asynchronous had a lot of different solutions.

    1. The definition of yes is a response to the affirmative it is the opposite of no. Stating a positive to a condition or set of conditions. We can go on all day here. The blog should always be used to discuss activities and assignment and you are always responsible for all work in your notebook. So I not sure why this is really even a question. See class policy.

  4. I am a bit confused as to what we are supposed to be calculating?

  5. Telstar 1 was the first active communication satellite to be launched, allowing TV signals, phone calls, and fax images to be sent across the Atlantic Ocean through space. Though it was only able to carry 600 phone calls and one black and white TV channel, it was still a major accomplishment.

    Telstar 1 was important because it was so groundbreaking in the communications world. Previously, transmitted signals stopped at the Atlantic Ocean, unable to be shared with both the US and Europe. Telstar's launch allowed for both official communication and news to be shared, however it could also share entertainment programs across the ocean.

    Geosynchronous orbit means an object will stay in the same spot relative to Earth. Due to the fact that the object orbits in the same direction as the Earth, it looks stationary when viewed from the ground. Satellites in this type of orbit are often used to monitor weather and transmit TV and communication signals. (Tends to be higher)

    Asynchronous orbit means an object passes over different parts of the planet at different times. This is the type of orbit that the Telstar 1 followed. Though Telstar's total orbit time was about 2.5 hours, it only passed over the Atlantic Ocean for about 20 minute periods, so this was the only time signals could be transmitted. Nowadays, objects in this kind of orbit are often used for photography, mapping, observing environmental changes, and locating deposits of important minerals.

    I'm also confused on the last question. What exactly is it asking us to calculate and find?

    1. For geosynchronous orbit what are the conditions that must be met. Look at what variable you have and what is still needed. Basically I am asking you how one puts a satellite in geosynchronous orbit along with the calculations to prove it. Yes you could probably look this up but that would defeat the entire purpose of the exercise. We are still struggling with critical analysis and POI. The only way will get better is to push through it.
