MobileMapper 6 vrs. Juno SC

I told them that I'm trying The MobileMapper 6, this week we will do field tests, but reading on the Internet I found that at the beginning of this year we wrote an article based on a test of comparison of these two instruments, here I will show you the most important of this comparative that can download Complete from this page.

The conditions

The MobileMapper 6 data was collected using the Magellan Mobile Mapping, with posttrending option, then corrected with the MobileMapper Office

Magellan trimble The Trimble Juno data was collected using ArcPad 7.1 and the Trimble GPScorrect extension, then the raw data was corrected with ArcMap 9.3 and the Trimble GPS Analyst extension.

Both devices were mounted on a pole, in order to capture data under the same conditions and time. The exercise was performed by measuring Magellan trimble A cul-de-sac, first measuring it with a ProNark 500 of 1 centimeter of precision to have it for reference and then with the two devices put to the test.


The results

The following graph shows the data obtained, before and after the post-processing. Yellow lines correspond to Trimble (five tours), blue lines to Magellan; see how after the adjustment, the capture of the MobileMapper is almost the same line.

In the next image are the data compared (already postprocessed), observe how the Trimble has serious problems when capturing the points in the two corners, at the foot of the building that makes interference, compared to the Magellan.

This is only visual, now let's see what happens if we compare with the real measurements in a table. Individual tables appear in the document as follows, but for our purposes I have put them together with a sophisticated program called MS Paint.

The conclusions

As you can see, all the Magellan measurements (in blue) reflect sub-meter precision, with a maximum of 0.70, with an average of 0.50. While those of the Juno (in yellow) range from 0.40 to 5.30 and their average is 1.90.

It seems that the BLADE technology implemented by Magellan makes this device generate precision results quite similar to what its predecessor known as MobileMapper Pro did, with Some more advantages And above all, at an unbeatable price if you consider that it provides sub-metric precisions.

Oh, as for price, this is the comparison, with prices in the United States, in March of 2009, including the software used.

  4. Good day galvarezhn.

    I would like to know if you happen to have any manual of the MobilMapper Cx, and that is that yesterday I was given one, but I sincerely do not know how to use and exploit its benefits since I had never had one of these devices in my hands. Besides, I see that in postprocessing, sub-metric precision can be achieved, but I do not know how to work it.

    Could you help me by telling me where to get some tutials?

    In advance, thank you very much.

  5. Very good Blog, the article is quite complete. I am waiting to try the equipment. I bought a pair and I'm waiting for delivery. It comes with external antenna and postprocess, so I think I can get 30 cm. In stop and go. Working with a Promark 2 working as a base. Having the results we commented.
