My task is to estimate / compute accuracy of a gps receiver. My experiment would involve using three GPS receivers and post processing software. following is the nomenclature i would follow for explaining my question. Normal GPS receiver: This is the receiver in test, a simple 12 channel...

Can anyone please explain schuler cycle, please don not start explaining with same old pendulum with the length of radius of Earth stuff. why is it required ? what is that all about ?

a must read before studying deep into aerospace are two books which i found to be very useful Introduction to flight by A C Kermode Aerodynamics for naval aviators these two are excellent books without any mathematics with maths and lots of theory introduction to flight by anderson...

In aircraft the frequency of operation of electrical systems used is mostly is 400hz. The reason given is that the size/weight of the equipment reduces as the frequency increases. can anyone please explain me the theory behind this with some formula, please do not stop with formula. How and why...

i understood the air flow properties variation in convergent divergent / condi nozzle or laval nozzle for subsonic flow based on the formula, for a incompressible flow : density * Area * velocity = constant as the total pressure in the flow is constant dynamic pressure is...

can anyone please explain me following errors of gyroscopes used in inertial navigation systems of aircraft : a) what is transport wander , how actually it happens ? b) what is apparent drift in gyroscope ? c) what is coriolis effect and how it causes errors in gyroscopes ?

Can anyone please explain me what is difference between Full Authority Digital Engine Control and ELectronic engine control in an aircraft gas turbine Engine ? What all parameters are controlled in EEC and FADEC ? What is the main difference ?

i understood brayton cycle etc.. but why is air compressed in the GT engine ? iS is anything related related to following reasons ? 1. FOr better combustion of fuel, if so why ? 2 IS it to increase the temperature of air, if so why ? 3 any other reason

hi karthick tried every possible way i mean took the component of A in the direction using trignometric functions but i couldn't get the answer as in textbook. answer as i ntext book is 21.29 knots in the direction t4 deg 47 minutes south of east

Homework Statement A vessel is sailing with a velocity of 11 knots per hour in the direction southeast and a second vessel B is sailing with a velocity of 13 knoths per hour in a direction 30 degrees east of north. find the velocity of A relative to B. Homework Equations The...

Homework Statement in a control configured aircraft the wind is oriented along V= 2i+7j+20k and with a magnitude of 45 knots. the aircraft is controlled to point along vector X = 4i+7j+3k at a speed of 2450 knots. Find the direction and magnitude of aircraft velocity vector ? Homework...

can anyone please explain me matched filter in detail ? my understanding is as follows ( in case of a radar). u transmit a signal and during reception have a filter in ur receiver which continously checks in the received echoes whether the echo has the same shape of the transmitted pulse. is...

is gauss elimination method same as gauss jordan method in matrices ?

Homework Statement In an inertial navigation system on switching ON an intial error of 0.0001m/s^-2 exists in one direction. After 30 minutes an additional error of -0.00005m/s^-2 in acceleration builds up. The system navigates for 2hrs 30 minutes after switching ON. compute the error in...
