Abstract – It shows how the mars rover communicates back to the earth. It includes a virtual Mars station and a virtual Earth station. The Mars rover captures an image and sends it to the virtual Mars station. Now the image is converted into a suitable signal so that it is transmitted to an orbiting satellite. This satellite sends the signal to the virtual earth station. It is converted to the original image on the virtual earth station. This signal is sent to another orbiting satellite if in case the communication with the first satellite fails. Key Words Used: Virtual Mars station, Virtual Earth station, Rover, Orbiting satellite
Deciding the distance between the two virtual servers so that they don’t communicate directly between them. This would be decided by using link margin calculation
2.2 Basic Working
1. INTRODUCTION
In Mars Mission (1971), orbiters/landers failed because of the contact lost between the Mars and the Earth Station. Thus the main focus is on how the rover on the mars would communicate successfully to the earth station without the failure of the orbiting satellite which would lead to the loss of information. Hence this paper focuses on how the rover would successfully transmit information to the earth from the Mars without information lost. Also it proposes an alternative for the probability of loss of information.
2. BLOCK DIAGRAM OF COMMUNICATION IN MARS ROVER
Capturing an image: 1. Stepper Motor would rotate the raspberry pi camera for 10 degrees/second thus rotating 36 times. 2. The images would arranged in a sequence to generate a panaromic image. This image would be transmitted using compression techniques like DCT, DWT, etc. to the transceiver IC CC1120 at the virtual mars station. It would then be converted to a suitable signal using BPSK Modulation technique Through the dipole antenna it would be given to the two orbiting satellites through free bands available of 144-148 VHF and 435-438 VHF. If any one of the orbiting satellite fails then the signal would be transmitted through the other satellite thus avoiding the loss of information. It would then be received through a dipole antenna at the virtual earth station and would be converted to the original format using BPSK Demodulation technique.
Transmission of signal to both the satellites so that even if one satellite would fail the other would transmit the signal effectively.
