Mr. Domag:


Altus can easily upgrade the APS-3 to what we call the APS-3G in order to utilize Galileo/Compass.

Here is a link contrasting the two units:

Is Altus upgradable? If I buy Altus now, can I upgrade it to support Galileo/Compass in the future? If so, how is it being done? Is it just a matter of firmware or hardware?

To the best of my knowledge Galileo is not yet supported but someone from Altus would be better to answer to the plans for when it will be. I would assume with Septentrio's ties to the European Space program it will be an easy thing to do if not already done.

Manual Offsets are specified by entering azimuth, vertical, and horizontal distance offset values. The vertical difference entered will be added or subtracted from the current GPS elevation, if no value is entered the value at the GPS position will be used. Laser Offset: For more accurate offsets, lasers can be used for either the distance (with direction and vertical offset entered by the user) or for both distance and direction (where the laser gun includes compass directions). The Leica Disto, for example, provides distance only. The Laser Atlanta provides both distance and direction. The laser devices are often mounted on the pole beneath the GPS antenna, enter the laser height above ground and go into the settings to enter the offset and height. More specific information on the settings can be found in the Carlson SurvCE manual.

Cold start* < 45 sec
Warm start** after power-on < 7 sec
Re-acquisition < 1.2 sec
*No information available (no almanacs, no approximate position)
**Almanacs and approximate position known, no ephemeris known

How fast Altus can fix point positions compared to Leica and Trimble of same class?
Reply by Arnel M. Domag on June 10, 2010 at 7:42pm
How vertical angles are managed using laser? If distance and azimuth or distance and another point are only required then to my point of view, it does only calculate horizontal position. How about relative vertical position?

Can it support Galileo or Compass in the near future? How does it work?

Yes, SurvCE allows you to do "hidden point" or as they call it offset (if I am on the same page as you). I think I have a document on my web page about calculating offsets in Carlson SurvCE. You can do them with a laser or by simply entering a distance and azimuth, or a distance and another point.

Does it support Hidden Point? How does it work? What additional measuring tool(s) is/are required?

thanks Paul...just added them to the video section of the site...
