1
Q
(IN)Accuracie devices
A
- Fix error:
*Diffrent nets- Dagr (12/10m)
- ori error:
- kompas: 40mils
- DMC vector 4/21: 10mils
- PLRF: 10mils
- JIM C: 5mils
- Dist error:
- Vector 4: 2/3m
- Vector 21: 5m
- double pass: 2,5/100m
- PLRF: 5m
- JIM C: 2m
2
Q
FIXATION METHODS?
A
- Trilateration
- GPS (cont)
- Direction/Distance from notable point
- On a notable point
- Road taken
- intersection of 3 directions
3
Q
Prerequisites trilateration?
A
- 400mils < ø < 2800mils
- Highest net as posible at least topo
- Angle ø as close to 1600 as possible
- RPs as far as possible
4
Q
Trilateration accuracy FIX?
A
- if RPs = UTM -> Max fixerror = 7m
- If 1 RP = topo -> Max fixerror = 7m
- If 2 RPs= topo -> Max. Fixerror= 50m
5
Q
Direction and distance known point?
A
You need a DIR and DIST of a KNOWN point. ( For HP use Calc didi)
6
Q
On a notable point?
A
This depends on the accuracy of that point. UTM is 0, map 50m, pigmap is topo zo 7m
7
Q
Road taken?
A
Pure map study. Accuracy is arbitrary (>50m)
8
Q
Intersection of 3 directions.
A
You need 3 points locatable on a map.
Your location is the center of the lines drawn in the map.
Accuracy Arbitrary (> 50m)
9
Q
Positrep you do via?
A
Via B-report.
10
Q
ORIENTATION METHODS?
A
- Trilateration
- POINT
- Notable point + known point
- Compass
- Römer + known point
11
Q
Accuracy Trilateration orientation?
A
- If A & B UTM: Max error = 1,5mils
- If A or B Topo: Max error = 4mils
- If A & B Topo: Max error = 4mils
12
Q
Accuracy Notable point + visible known point?
A
You calculate with the formula of ‘accuracy distance’
13
Q
Until what distance can you determine tgts in mapnet?
A
- FO will always calculate beforehand the Max distance where hè can localise tgts with a min accuracy of mapnet.
- this hè does with the ‘dk formula’
