## HP SCATTERPLOT Netherlands

## HP Convergence

## OmniSTAR HP INITIALIZATION TIME

-   Improvement and implementation*:*
- Use known point as start value: Within 2 minutes
- DGPS as start value (50 cm direct, 10 Min for 30cm
- Static Convergence: 15 Min
- Re-initialization after
- 	loss of signal <5  minute :Direct HP

**OmniSTAR HP INITIALIZATION TIME**

## OmniSTAR 8300 HP Initialisation test

## HP Convergence over 80 hourly sample

**Estimated Standard deviation**

**Real Standard deviation**

## Convergence is dependant on Geometry

## HP Re-initialization

**How to go get back to HP accuracy**
** ****in a tunnel or **
**going under trees**

## Challenging environments

## Re-Initialization

- Static receiver
- September 2003, Lafayette, USA
- 69 gaps of 20 s (average)

## Re-Initialization, results

- Success rate: 98.5%, average error: 0.05 m

## Static re-initialization tests

## Omnistar HP dynamic re-init test

## Dynamic re-init accuracy 

## HP Extend time without Correction

## Trees at high elevation

**Trees at high elevation**

## HP Age of correction 4 minutes

**HP Age of correction 4 minutes**

## No Network correction for 4 Minutes
