I am very excited to share my first simple DGPS survey setup using readily available parts and Reach for a quick field campaign. I used a 10Ah power bank to power the reach module and a tupperware small box for Tallysman antenna.!
I’ve kept a small aluminium foil as a ground plate. Although the diameter of the ground plane is smaller than suggested 10cm, it worked fine. I’m trying to increase the SNR. I have a small question that what type of material is required for antenna cap for getting more signals. Your suggestions are needed. I will process the raw data and upload the images soon.
Thanks once again the Reach team for making survey so simple and cheap.
I wouldn’t use any housing for the antenna when the antenna itself got a housing already.
I have got two Tallysman antennas, a TW3710 and a TW4721, and both are IP67 rated.
This means they are dust proof and could be submerged into water up to 1 meter for up to 30 minutes without taking damage. That should be enough for outdoor use I would say
Interesting, I’ve used Reach and worked hand in hand with the US Army Corps of Engineers on plots as big as 140acres. I’ve been given thumbs up multiple times,
I understand @pavan008’s point, but since this thread is not about long-baseline geodetic survey, his comment is off topic. In short, he means that multi-frequency GNSS receivers can maintain accuracy at much longer distances than single-frequency receivers. It is true, but not related to the subject of this thread which is low-cost surveying, a market niche where Reach devices are most certainly at the top of their class.
