ArcPad is receiving NMEA data and the Z value is an ellipsoid height, not orthometric. You have the ability to put a geoid separation value in ArcPad, so I would recommend looking into what your separation value is for your project area and enter it. If you are in an area with a extreme terrain changes, your values could vary a lot from one area to another and this value changed accordingly. All said, the Juno is 2-5 meters accuracy in the horizontal, so I would say 3-10 meters in the vertical at best. Do not rely on your Z value to be all that accurate with devices that provide this level of accuracy.  ... View more

Esri has partnered with Leica Geosystems to offer a high-accuracy GIS/GNSS field collection solution running Esri Collector for ArcGIS called the ZenoCollector. This would offer sub-meter to 1cm accuracy in a fully integrated solution. Here is the landing page on Esri's site: ZenoCollector​ ... View more

It sounds like this is what you are looking for in order to edit the attributes of a previously collected feature. http://help.arcgis.com/en/arcpad/10.0/help/index.html#//00s1000000r1000000 ... View more

""Editing" is fairly vague. Do you mean edit the geographic location by storing a new GNSS measurement, edit the attributes of a feature or some other form of editing? I would recommend reading over the online documentation regarding editing. It can be found here: ArcPad Help ... View more

You can download Ashtech related firmware, etc. here: Ashtech Latest Firmware/Software ArcPad can be upgraded through Esri. To go to the latest version I believe you have to have maintenance on the product. Here is a link to the latest ArcPad build: ArcPad | Try it Free - Download ArcPad Evaluation Software . Once you have it installed you can license the evaluation version with your updated registration code. ... View more

Ashtech was bought by Trimble several years ago and is now under the Spectra Precision brand. Here is a link to their support page: Support - Spectra Precision If the MM100 unit is connected to the RTN and receiving RTK corrections and NMEA output (COM 2, baud rate of at least 38400) is set up correctly ArcPad should be receiving the data if your COM port and baud rate in ArcPad's GPS preferences are correctly set. If the equipment hasn't been used for some time it may be best to do a GPS reset. GNSS is certainly capable of sub-foot to 1cm accuracy when correctly configured and used appropriately. ...

When the "Welcome to ArcPad" dialog box appears upon start up there should be a toggle box in the lower left hand corner that allows you to select and then make your selection of "New Map" for example. Also, under the ArcPad Options menu>General tab, there is a dropdown box so you can select which process you would like upon the starting of ArcPad. ... View more

The Handheld USA Algiz 7 manual has specific instructions for configuring the GPS. It states that the GPS is on COM3 with a baud rate of 9600. ... View more

From the spec's of the FZ-G1 it uses a SiRFstar III chipset, which is roughly 2-5 meter accuracy at best. ArcPad does not directly store raw data for you to deferentially correct the data, so that is not an option. If you need improved accuracy, I would recommend looking at the Leica Geosystems GG03 SmartAntenna (link below). This would offer sub-meter accuracy when using SBAS corrections, or improved accuracy to 30-50cm if using a real-time network correction. If you were to add the L2 option, you could further improve that to 1cm accuracy if needed. If using ArcPad, Zeno Connect for the tablet would also be needed. Connections from the GG03 to the tablet can be done via bluetooth or a cabled connection. http://www.leica-geosystems.us/en/Leica-Zeno-GG03_99885.htm ... View more

Hello Trisha. What type of positional accuracy are you looking for out of the tablet? I would recommend taking a look at the Leica CS25 GNSS unit. This is a Windows 7 ruggedized tablet PC with an integrated high accuracy GNSS board for ~0.9 meter accuracy using SBAS as the correction source down to 10cm or better when using the tablet as a handheld device. You could increase accuracy to 1cm by adding an external antenna kit as well. The Zeno Connect software allows you to utilize the high accuracy GNSS in Esri ArcPad.

Jamal, There are a lot of unknowns about your network, how you are configuring your project, ArcPad/Zeno Field, etc. You had mentioned prior that you are modifying the GPS datum in Zeno Field, which is not recommended as all transformations are handled by Zeno Office/Zeno Office on ArcGIS. Also, what coordinate system is your GPS reference network sending the corrections in? I would highly recommend some level of training (on-site or web-based) as I do not experience any of the difficulties that you have to date. When I connect to a local real-time network (RTCM3_IMAX mountpoint), receive RTK corrections to 1 cm and check into a control monument with established coordinates I check well within the GNSS accuracy stated by the GG03. If you set the GG03 up on a known point, are receiving RTK corrections to a phase-fixed 1 cm solution and are not moving while storing 3 separate points, all three of the X, Y, Z values of these survey points in Zeno Office/Zeno Office on ArcGIS should be in the centimeter range. If not, you have a configuration issue. ... View more

If receiving RTK corrections and my estimated positional error is at 1 cm then my coordinate values are all well within specification. You should compare your X, Y, Z values. ... View more

What was your estimated positional accuracy? I would assume you did not have a RTK fixed solution at the time so that is why the coordinate values varied. ... View more
