Your instructor has developed a survey for the class to try to help determine the effectiveness of the class to this point- The problem is, your
instructor has not developed a survey in quite some time and the survey items are in need of some repair. Please identify the problem with each of
the following survey questions and explain why the wording or the use of this problem will make interpreting the results of the survey difficult- Then
rewrite each survey question so that the problem in question is avoided-
1- Do you feel that the class should not include quizzes?
2- Do you complete discussion on time? How about readings? How about the assignments?
3- Do you think students would fail the class if they do not submit their assignments?
4- Would employing a Z-score grading scale more accurately reflect student performance relative to their peers?
5- Should more time be provided for quizzes and discussion?
Satellite Communication Systems Overview Distributed: 23rd March, 2015 Last Edited: eleventh December, 2017 Disclaimer: This article has been put together by an understudy.

SATELLITE COMMUNICATION SYSTEMS OVERVIEW Satellite correspondence empowers two Stations on the earth to impart through radio communicate which are situated far from each other. The two stations utilize satellite as a hand-off station for their correspondence. One of the earth station will transmit to the satellite. This is called as Uplink. The satellite Transponder will change over the flag and sends it down to the next earth station. This is known as a Downlink. The satellite correspondence is beneficial over earthbound correspondence on account of the enormous scope territory and high data transmission capacities. The inconveniences of satellite correspondence are vast engendering delay, correspondence cost and slow increment being used of transfer speed. The fundamental elements to be considered in satellite correspondence are; height point is the edge of the earth surface to the inside line of the satellite transmission shaft. This edge gives extensive impacts on satellites scope region. In a perfect world, height point ought to be 0 degrees, with the goal that the transmission pillar will achieve the skyline unmistakable to the satellite every which way. In any case, there is a base rise edge of earth stations in view of the natural elements like items obstructing the transmission, barometrical weakening, and earth electrical foundation commotion. Scope edge is the measure of the part of the earth surface noticeable to a satellite considering the base rise point.  It is indicated as, R/(R+h) = cos (β + θ)/cos (θ) Here ‘R’ is earth span (6370 Km), ‘h’ is satellite circle stature, ‘Β’ is scope point and ‘?’ is the base height edge. There are impedances like free space misfortune, air lessening caused by rain and haze will make significant impacts amid transmission.  There are distinctive sort of satellite administrations in particular, Fixed Satellite Services (FSS) to offers point to point correspondence. Communicate Satellite Services (BSS) to give satellite TV and radio. Portable satellite Services (MSS) will give communication. There are number of satellites circling in various circles.  The kinds of satellite circles are (GEO) geostationary earth circle, Medium earth circle (MEO), Low earth circle (LEO) Molniya and tundra orbit.GEO satellites are in circle 35,863 km over the world’s surface along the equator. Questions in Geostationary circle spin around the earth at a similar speed so as the earth turns. This implies GEO satellites stay similarly situated in respect to the surface of earth. This satellite has substantial scope zone which right around one fourth of the world’s surface. It has 24 hour persistent perspective of the specific locales of the earth, so it is utilized for broadcasting and multipoint applications. These GEO satellites experience issues in communicating in close polar region.LEO satellites are substantially nearer to the earth than GEO satellites, running from 500 to 1,500 km over the surface.LEO satellites don’t remain in settled position with respect to the surface, and are noticeable for 15 to 20 minutes each pass. So a system of LEO satellites is important for LEO satellites to be helpful. A LEO satellite’s vicinity to earth contrasted with a GEO satellite gives it a superior flag quality and less time delay, which is better for point to point correspondence. A LEO satellite’s littler region of scope is to a lesser degree a misuse of transfer speed. Air drag influences LEO satellites, causing continuous orbital disintegration. A MEO satellite is in circle somewhere close to 8,000 km and 18,000 km over the world’s surface.MEO satellites are like LEO satellites in functionality.MEO satellites are unmistakable for any longer timeframes than LEO satellites, ordinarily between 2 to 8 hours.MEO satellites have a bigger scope region than LEO satellites. Tundra and Molniya Orbit Satellites are utilized by Russia for a considerable length of time. Molniya Orbit is a circular circle. The satellite stays in an almost settled position with respect to earth for eight hours. A progression of three Molniya satellites can act like a GEO satellite. It is helpful for activities in close Polar Regions.  International Telecommunication Union (ITU) has done the recurrence distribution and making arrangements for every satellite administration. To encourage effective recurrence arranging, the entire world is partitioned into three areas.  They are, Area 1: Europe, Africa, Mongolia Area 2: Greenland, South and North America Area 3: Australia, Asia, South west pacific Recurrence band are assigned inside these districts to give different satellite administrations. A portion of the satellite administrations are Broadcasting Satellite Services, Mobile satellite administrations, settled satellite administrations, Navigational and meteorological satellite administrations.  Distinctive sorts of satellites utilize different recurrence groups. They are given in the table beneath, FREQUNCY BAND Working FREQUENCY (GHz) Sorts OF SATELLITE SERVICE USES L-Band 1-2 MSS S-Band 2-4 MSS C-Band 4-8 FSS X-Band 8-12.5 FSS Ku-Band 12.5-18 FSS and BSS K-Band 18-26.5 FSS and BSS Ka-band 26.5-40 FSS>
