CHC i80’s Shipping from iGage

Okay, this is a year late probably. But we (iGage) have actually shipped a couple of i80 pairs!


The ‘iGage i80 User Manual’ is complete (other than antenna calibrations) and the iGage Download Tool recognizes the i80 and successfully can pull data files from the i80.

There are a few gotchas:

  1. We don’t have antenna calibrations for the i80, however robotic calibrations are in progress and expected soon.
  2. We don’t have heavy duty power cables for the i80, however they are in progress and expected within a week or two.
  3. You have to run SurvCE 5.0 beta (which is called 4.90.31 currently.)
  4. The tilt compensation and calibration does not work in SurvCE (this must be a software issue because the CHC Landstar program appears to work well with the MEMs functions.

Other than that, you could conceivably place an order and have a pair shipped to you (the next shipment arrives at our office around the 27th of January.)

Call for pricing, it is not nearly as bad as you would expect…

End of the Road for PM700, MM300

Spectra Precision has announced end of shipping of the ProMark 700 [and we could assume the MobileMapper 300 soon.] We (iGage) still have at least one more PM700 available.

The ProMark 700 was a BD930 based L1+L2+G1+G2 network rover (no UHF radio) in a simple package (small pole top antenna) with killer performance.

pm700RIP ProMark 700

The replacement is the SP60, which basically does everything the PM700 does and adds a replaceable battery.

sp60Long live the SP60!

Yes, there is a slight change in price: SP60 =$10,950; ProMark 700=$7,995 ($3,000).

But the SP60 has the possibility of having a UHF radio added to the bottom (same as the SP80.) If you are wondering, the list price on the SP60 with UHF is $12,450 and the list price of the SP80 with UHF is $13,995.

And yes, I agree that it is totally worth $1,545 extra to get the SP80.

sp80_1392084456291SP80 Rocks!

Because the SP80 has: Dual hot swappable batteries, Tilt Sensor, Display, Built-in Wi-Fi, nice button interface, built in Web Server… and more.

Both the SP80 and SP60 utilize the same GNSS Engine which is the best performing engine (in the open and under canopy) available today.

SurvCE: N-Point Localization

Here is another preliminary chapter from the presentation I am going to make next month at [GoWest]:

Show how to localize a complex lot. First with two known corner pins, then using the initial localization to find the remaining corner pins.

Make a new job with a reasonable base projection, this lot is near Huntsville Utah so Utah North NAD83 Survey Feet is reasonable. Here is a topographic map showing the parcel and its approximate alignment with roads… [ NPointLocalization]

SurvCE: Low Distortion Projection Example

Another chapter from the presentation I am making next month at ‘GoWest‘:

You can configure a precise Low-Distortion-Projection in SurvCE quickly while in the field. This projection will have the advantage of being aligned to True / Geodetic North at the base point and will effectively have a scale factor of 1.0 at Ground …  Continue reading [ LDPExample ]

Getting Local Coordinates into a Job

Another section from my ‘GoWest‘ presentation:

To Localize we need to get the local coordinates (the coordinates we want our instrument to read) for our affine points into SurvCE. We can type them directly (File: Points: Add); however, it will save us a lot of time and reduce the chance of error if we have them already loaded into our job… [ Continue reading [GettingLocalCoordinatesintoaJob] )

SurvCE: How Do You Un-Localize a Job?

I am going to be speaking at the Carlson ‘GoWest’ conference in Las Vegas this February
( click [ Here ] for more information)
and I am preparing my topics and examples.

I don’t think that it will hurt to break them into pieces and pre-release them here on my blog.

“Even though this topic is SurvCE Localizations, let’s start out with what you need to do if you want to work with a Base / Rover pair in State Plane Grid coordinates; starting with your base at a point with a known State Plane Coordinate. In other words, the opposite of localization…  [continue reading:  UnlocalizingAJob ]”
