Is an MHRS the same as a heading system??

I have to answer a question regarding an MHRS (magnetic reference heading system). I can't find much information online at all, though i have blindly stumbled onto heading indicators which rely on flux gates as well as a directional gyroscope.

Am I reading about the correct thing, or am I way off?

As far as I can tell, a heading system is made up of four component parts,

HSI
Slaving control compensator unit
flux gate
Directional Gyro

It is used to provide the pilot with heading information with a reference to magnetic north and its advantages/ disadvantages over a stand alone compass are as follows:


Advantages

• Does not suffer from dip error.
• Does not suffer from accelerating error.
• Less susceptible to deviation error.
• Able to provide more information/ more comprehensive system.



Disadvantages

• Cost.
• More components, more prone to a system failure.
• Subject to gyroscopic errors.
• Can ‘topple’ during abnormal flying conditions.



Please excuse my naivety, I am an electrical engineer but have to complete an integrated flight instruments to gain all of my modules.
