Significance of the Al Khalid

BMS? What kind of BMS does Al-Khalid has? I dont quite understand.

Battle field management sytem, right? I don't know the specs of it, but it is Pakistani made and it has been sold to the UAE about a year and a half ago.

The Al Khalid has a BMS. As to how effective the BMS is, well, the UAE did buy it from Pakistan and considering the fact that the oil rich countries have enough money to buy almost anything they want, the BMS must be decent.

The UAe hasn't got the tools to operate a BMS...they got less than 10 UAV's and all their Satellites are civilian telecom ones. That means If they have to cut the line to operate a BMS customers may get angry...:nono:

Anyway pakistan has a BMS? Do you know if it's a parallel/Dual sytem. If it's a prallel then it's useless agaisnt India.

the Pakistani BMS see below

LONDON [MENL] -- The United Arab Emirates been discussing a major project that would deliver a Pakistani battle management system to Abu Dhabi's ground forces.

Industry sources said the UAE Army and Islamabad have been negotiating to acquire a Pakistani BMS that would link main battle tanks, armored personnel carriers and combat vehicles in Abu Dhabi's military. The sources said the system would be capable of forming a network comprised of a range of Western platforms in the UAE land forces and would not require the purchase of Pakistani military platforms.

The Pakistani system was identified as the Integrated Battlefield Management System. The network was meant to link armored forces and provide them with situational awareness and identity friend, foe capability.

The sources said the Pakistani system was not as advanced as Western networks and could not be regarded as network-centric warfare. The system was said to employ Very High and Ultra High Frequency radio communications, with each vehicle capable of serving as a relay.

Indian tanks use GPS and frequency hopping radios !!!

The Al Khalid also uses GPS, but I don't know about the frequency hopping radios.

GPS is a common system but they are vulnerable to US !! In future Indo-Pak conflict US may jam or downgrade GPS signals rendering communication systems and GPS guided bombs (do PAF have this ?? ) useless !!!

India also uses its home grown satellites for communication . Actually for civillian communication in India there is a little room for GPS , Insat satellites do the job.
But I really donno about their depth in Military uses, its secret !!!


Any electronic engineer here ???
Any body to explain frequency hopping , VH,UH frequency radio signals !! How they can be jammed or are they jam proof ???

China also uses GPS for some of their weapon systems, but I am not sure how reliant China actually is on the GPS system. Anyway, I am not an electrical engineer (not yet anyway), but I have yet to hear of jam proof radios. MAYBE hopping frequency radios can be jam proof, but I will have to do more research on that.

Well, many of the Chinese systems use both GPS and GLONNASS. I'm presuming a switch to galileo would happen once that system becomes available.

I don't see why the Al Khalid or any other tanks cannot be modified really easily to use other navigational networks.

As much as GPS and Glonass are great they aren't under anyones control exept US and Russia. In the future India will have partnership of Glonass. BTW GPS is no big deal. UAV and live images are important.

The above statement is true.

They are likely to be used for military purposes also.

As an example, just as a kitchen knife can be used for cutting fruits or for stabbing, Indian remote sensing satellites (the densest cluster in the world), are probably used for this purpose also, although ISRO never publicly announces it.

Frequency hopping means that the 2 communicating entities (such as 2 cell-phones communicating via bluetooth), switch (or hop) the frequencies of communication after every fixed interval of time. The increments in frequency and the time period of transmission in one frequency before jumping to the next--must be mutually decided upon by both. Protocols exists for this purpose.

In other words say I'm talking to you at the frequency of my voice for 1 second, at an Opera singer's frequency the next and at a small girl child's frequency the next second.
So I am "hopping" in frequency transmission.

If a third entity somehow knows the hopping frequencies with the time period of transmission ( 1 second for each in our example), then it can send noise signals on those frequencies to disrupt our communication.

So he may shout mimicking my voice at the first second, sing badly at the opera singer's voice the next second, and cry loudly at the girl child's frequency the next second--if he wants to disrupt the communication between you and me.

VH and UH signals are not jam proof. If the enemy knows the communication frequency, it will send "noise" or jarring signals at the same frequency to disrupt communication between pilots or the datalink between a passive guided missile and the home radar.

The Trishul SAM missile is a very good example of frequency hopping. It is a passively guided missile.

At first it is injected in a high frequency, then on a medium frequency then a pencil beam frequency (40 Ghz). So even if enemy jammers manage to noise one part of the frequency, in a few seconds it would have switched to the next one, thus making jamming very difficult.

Due to this capability,Trishul is one of the best passively guided quick-reaction SAMs in the world.
