Q I od Incognito (2) 16065325 2 / 3 50% + a Consider the modeling of the Signal-to-Noise Ratio (SNR) for a satelite (sat) communication system EXERCISE 1 To be submitted within the Laboratory period) - linked to an earth station (et) with the following parameters: 1. Radius of Earth (R.) in km 6400 km 2. Radius of satelite above earth's atmospherer) in km-Input variable 3. Central angle in degree - Output 4. Longitude of satelite in degrees long) - 68.5°E 5. Longitude of Earth Station in degrees (long) = Input variable 6. Frequency of transmission in GHz (Fax) = Input variable 7. Gain of transmitting antenna in dB (Ge) = 15 dB & Gain of receiving antenna in de (G) = 15 dB 9. Stefan-Boltzmann constant (K) 1.38 x 10-%/K 10. Noise temperature of receiving system in Kelvin (T) - 190 Kelvin 11. Bandwidth of the receiver system in Hz (B)-75 X 10 Hz 12. Received Signal Power in de (P) = Output 13. Transmited Signal Power in dBm (P.) = Input variable 14. Path Loss in dě (L) = Output 15. Signal to Noise Rato (SNR) - Output Bidant In order to calculate the SNR during signal transmission from space to earth, a parameter which gives a statistic of the amount of signal present during transmission, we employ: SNR=R-P [dB] (1) Where P, is the received power level in dBm and Pis the noise power in dB Mathematically P,= P. +G+ G- [dB (2) And, P. = 10Loy.. (KTB) IdB] (3) The path loss. L. is the amount of transmitted signal los due to the effects of travelling through space and earth's atmosphere. The path loss in dB is given as L = 92.44 +20Logu (Dotel) +20Logo(Faux) [dB] (4) Descalis referred to as the slant range, a parameter representing the actual distance between the earth station and the satelite given by: Dental = R' + r2- 2rR.cos [km] (5) Where B = Cos-Sin long st)Sin (longat) + Cos(longust) Cos(longer ) Cos(m) [degrees 2 w = long.at longer" "If longcat and longer belong to the same longitude i.e. both "E or both W, use the negative sign F long.at and longat belong to the different longitude ie. "E and W or vice versa, use the positive N Your Tasks in this Laboratory Using windows forms and writing in C++, design an application that can be used to estimate the SNR of a typical earth-satelite communication system using the given parameters as provided. For this purpose please note that the summary and interpretation of the required parameters are given to help your understanding. For the proposed application, please note that items 2,5, 6 and 13 are to be your input variables, while items 3, 12, 14 and 15 are the output variables. It will an added advantage to you if your designed GUI shows attempt of creativity, innovation A REPORT must be written and submitted with respect to the Gul application being built in the A. Thereafter, using your completed GUI, provide answers for the following para ng parameters in this use-case Scenarice. Note that longer gaat is no longer a constant as previously y designated 1. For Low Earth Orbit (LEO) satelite in positional orbitatlong at = 15°W r = 1500 km, longe = 10°W.Foue = 6 GHz, P = 120 dBm 15 Points) 2. For Medium Earth Orbit (MEO) satellite in positional orbe at long at = 30°E = 10500 km m. long. = 40"E, Pon = 12 GHz, P. = 75 dlm 5 Points) 3. For Geostationary Earth Orbit (GEO) satellite in positional orbit at long.cat = 69°E r = 36000 km. longet = 59°W.Foka = 40 GHz, P, = 65 dBm (5 Points! B. What are your observations when P = 0dBm in all cases of LEO MEO and GEO as given above? Explain your results 5 Points i AJx 14:23 2022/05/17
