Been reading the FAQ’s, Documentation, using search. Still managing to come up with what appear to be basic questions that I somehow just haven’t spotted any clear explanations for
I have purchased a Reach RTK in used condition off of ebay, without the antenna or cables or anything beyond the bare module itself and it’s cardboard box. The ReachView app reported it’s version as 0.4.6, which I have since updated to 2.9.1. I purchased a GPS-only kit antenna, just to get going with. I am assuming that this antenna will not be good enough in short order as the status page SNR graph only shows one signal in green and the live map shows a point cloud looking about as precise as what I would expect to get from my Garmin GPSMAP64
For trial testing, I set the rig outside on my roof and attempted changing the settings for a static stand-alone mode without any outside source of corrections, as I will need this to function as the fixed base-station in a remote area 5 miles beyond any cell signal and 20 miles from the nearest data-capable cell signal
Didn’t spend a lot of time before updating, but the old app version seemed more intuitive for myself to understand, so now for a few questions
On the sidebar, next to the gear icon for settings, there is an icon that looks like a lightbulb. When I hover over it, no message box pops up to explain it’s purpose, clicking on it makes it blink like something is happening. Nothing has quit working and the RTK module didn’t immediately begin generating magic smoke
So what else could this icon be used for?
I set Base mode/Base coordinates to ‘Average single’. This results in a convincing looking set of numbers, but on changing back to the Status page the ‘Base position’ line remains all zeros. I was assuming this line reports on the modules base position? Is it for the position of an external source of corrections? Something broken? Need that better antenna? Documentation does not explain the underlying logic for how this line is filled-in
This module is supposed to have an onboard 3-axis accelerometer. In: 'RTK settings/Max acceleration, I set both settings to zero, yet the status page still shows accelerations in all axes? Does this mean the status line is for apparent velocity based on GPS fixes? Why isn’t there any page to show live readings on the onboard sensors? Are they disabled? If so, does this mean the maximum velocity settings are for GPS based calculations of movement? And when will this module get inertial navigation? I’ve had an idea about 5 years now that requires this type of data in a handheld GPS receiver. Be nice to see if it can be done here, finally!
Status page shows ‘RTK parameters’, with three stats shown. Each of these has a colored circle underneath. No explanations given as to what the colors mean, or how they are chosen. Also, no clear explanation on if these parameters are determined by any settings changes I make or if this is something being measured. Currently showing as all zero’s/green-red-green
On the ‘Base mode’ page, I keep seeing the position being recalculated, even though I have not restarted the module. It’s been continuously powered-on about 35 hours now. Would have been longer except for a technical issue with circuit breakers. Am thinking about doing the battery-pack portion of this project sooner than later & adding in a continuous charger for testing purposes
Also on this page, there’s a list of RTCM3 message types that I can select. Any chance that interface can be changed to have each type link to a wiki-page for people like myself who are still learning what RTCM is all about? I tried googling a few of those, but I have to wade through a ton of sales pitches giving me anything but relevant information. I know this can be done because on the ‘Camera control’ page, there is a link explaining what the ‘time mark pin’ is - though unfortunately this link appears to be broken as it gets a redirect to the introduction section of the documentation, leaving me to searching the online site. Perhaps an update is needed to have the link pointing to the right sub page?
Reminds me of something else. My original reason for buying this RTK module is to transmit corrections from my own base station to a handheld Garmin GPSMAP64, which states in it’s documentation that it accepts ‘RTCM’ messages but Garmin documentation does not make it clear which version it accepts or what message types. Anyone here happen to know anything about such interfacing issues? Possibly a question for the Groundspeak forum…
If you see that I did not ask about other items concerning the ReachView application, it’s either that they were sufficiently obvious enough or that I didn’t know enough to question! Thank you
