Compass
-
Am curious as to what type of compass is best for land navigation. Would a simple "Silvia" compass be sufficient or do I need something which includes Azimuth readins?

Sneak in a Garmin GPS...
The standard issue compass works nicely, but it does not go well with maps. -
Nah, not in service yet. But just curious in whats the diff. between the compasses avb. on the market.Originally posted by SingaporeTyrannosaur:Sneak in a Garmin GPS...

buy ure own gps uh.....
non of my officers actually use compasses...all got gps...
SAF one okla...kinda accurate if u issued with a good one.. -
i would trust a compass in mils than in degrees...Originally posted by SpecOps87:Nah, not in service yet. But just curious in whats the diff. between the compasses avb. on the market. -
Electronic stuff will fail
good old compass is still the best -
No man, if you have used a GPS you'll know just how useful it is in finding your way around. It's certainly makes you topo far, far easier. Comparing the compass to it and saying that it is the best simply because the electronic GPS can fail is like saying a club is a better weapon then a rifle because it cannot run out of ammo. Apples and oranges, they're very different.Originally posted by justcooler:Electronic stuff will fail

But of course, having a GPS it does not mean you can slack off on knowing how to use traditional topo methods with a compass and map. -
Agree, I would say that they are meant to complement each other then to completely replace each otherOriginally posted by SingaporeTyrannosaur:No man, if you have used a GPS you'll know just how useful it is in finding your way around.

for traditional compass, go for francis barker. -
For simple local navex, a normal compass or something that points north is more than enough... You can't really get lost in sg, with all the tracks and trails...
Unless you're doing a topo exercise that requires you to 'shoot mils', those 100m by 100m compass course, but then they would issue you prismatic compass
For foreign topo, GPS is super useful. At least you can leave the guess work out of your navigation. -
Having said all that, though I like my Garmin, if I did go for proper topo I would pack a good compass along just in case.Originally posted by SpecOps87:Agree, I would say that they are meant to complement each other then to completely replace each other -
compass might not be accurate as GPS. compass rely on the magnetic field..

The bloody azimuth lesson during my course has left me man. No longer recall a thing from it. I usually do my map reading my dead-reckoning and utilizing the available terrain features.

Aiyoh why like that? Azimuth reading is important sia...
-
Paiseh...Super Paiseh...cuz take it for granted that you never will go lost in SG. So aft the test, in Apr, last yr, everything return back liaozOriginally posted by SingaporeTyrannosaur:Aiyoh why like that? Azimuth reading is important sia... -
u can't use GPS under thick foliage
compass skill is still a must -
I wonder how hard is it to "knock" out 1 or more GPS satellite and have a theatre wide GPS "black-out"?
now that China have a anti-satellite capability, it might be something to consider... -
Actually hor... GPS is as useful to the enemy as it is to you as well... it is extremely unlikely that they want to deny it totally unless they have totally no GPS ability at all. Even insurgents use it if they can.u can't use GPS under thick foliage

Must be a strange jungle to have absolutely no clearings at all
GPS reception in my Garmin Vista gets scrappy when I am in foliage, but it still works rather well unless you are in a very narrow valley or something and the foliage is like those American redwood trees...
The latest models have no issue with that though... they can recieve signals indoors and under concrete! I wonder how that's possible?

Knocking out 1 GPS satellite does not bring the entire network down, it only leads to a increase in the error radius of the GPS. As long as you have an LOS to 2 sats you have your location, 3, your 3D location. Having more sats just makes this a lot better. To really knock out the network you have to clear the full horizon of your sky to make sure there is at most one sat left... not really easy considering those low on the horizon are on the other side of the world. You could wait for them to move into range though.
It is unlikely for China to try for GPS satellite unless things are really desperate. A lot of their own stuff function on GPS technology as well. Spy stats are a hotter, and more logical target. -
go get a silvia compass and check does it have the Azimuth readins???????Originally posted by SpecOps87:Am curious as to what type of compass is best for land navigation. Would a simple "Silvia" compass be sufficient or do I need something which includes Azimuth readins?

Army teaches you map reading and use of compass for good reason. The GPS is complementary. GPS signals can be spoofed or jammed. You can always find your way by going back to basics by using map & compass.
Navy teaches use of sextant for same reason.
One must not depend 100 % on technology.
