Another Breakthrough by Pakistan's Defence Sector

[Type59]

GPS jamming/spoofing tools are not something new.

Libya had invested a great deal in these technologies:

However, NATO humiliated Libya in the war: https://en.wikipedia.org/wiki/2011_military_intervention_in_Libya

FYI: https://www.technologyreview.com/s/423363/how-cruise-missiles-would-beat-gps-jammers-in-libya/

Their is no guarantee that these tools will deliver against threats which are jam-resistant to large extent.

Libya should have invested in wmds. Worked for North korea.

They did, then they abandoned it. North Korea won't repeat that mistake.

Its mainly for small recreational drones (even if being used by military they are simple technology, a remote controlled drone equipped with a camera for area/post monitoring). The main purpose is to have them at air bases and other military installation so they can bring down any RC drone in the area that is being flown for fun by some kid (and may cause aircraft damage to landing/taking off airplanes) or for area recon by some criminal!!

Good gadget for base security.

When we feed a "false GPS" signal (replacing the real GPS), we use "small drift to gradually lead the enemy off course or make them land in our own country (like Iranians did). So US would look for drift by using say inertial (e.g.laser rate gyro) among other sensors to estimate vehicle state (i.e. position velocity) etc. Then use these state estimates to find out vehicle's position and then correlate them with GPS signal received. If the position estimates are close in range, then both GPS and state estimates closely agree and received GPS is probably true.

Hi @Allahistan
It is possible to design way point based navigation "without" GPS entirely. One can estimate their location in earth-fixed inertial frame using the position equations i.e by integrating them. However for that one would need good sensor data for V,alpha,beta and IMU data. This problem is known as "observer design" problem(as in many cases V,alpha,beta are not available for measurement and hence you estimate their values using an observer). Now the main problem here is the accuracy and drift(in case of gyro) of your sensors. You have basically translated the problem of estimating your position to problem of accuracy and drift of your sensors.
This scheme is very resilient as it is very difficult to hinder the operation of IMUs or simple pitot(giving velocity readings) or AoA measuring sensor(giving AoA: note a similar scheme can be used to measure beta).
With very very high quality IMUs--like the one used in the case of modern ICBMs, it is indeed possible to design a system that can navigate without having to use GPS--only relying on the sensor data of lets say V,alpha,beta and IMU(p,q,r,phi,theta,psi). But such a system demands IMUs with very very small drifts.
