SMA26 Plus GNSS RTK Rover & Base Surveying Equipment with Controller and Software, Connect with UAVs,1cm Accuracy, NOAA Certified, IMU/PPP/UHF/NTRIP/BT, IP67 GPS for Civil Engineering and Topography

We purchased this to be used in place of, or in supplement to, a total station for survey and mapping on an archaeological project. We had been hearing from colleagues for a few years now on the merits of a dGPS in an archaeological setting and this year we felt it was time to jump on the bandwagon. This product did not disappoint. First, I will admit that what drew our attention first and foremost is the price. The fact that we could purchase not one, but two units (one to serve as a base and the other as a rover) for less than $3K, which is what we would be paying for one decent used total station, was mind-blowing. Reading the reviews gave us pretty good confidence in the product, so we pulled the trigger. The reason why we're writing this review is, however, not because of how little it cost, but how well it performed in the field. It took literally minutes to figure out the settings, thanks to little details like voice notification from the units themselves, clarity of the UI of their software (SMA Survey), and some helpful videos on YouTube. As with any new ecosystem, it takes a while to figure out what's going on (it took a little while for us to work out how stakeouts work), but once there, everything became a breeze. We were collecting topo data at the speed of walking, literally. Tilt compensation is a game changer for mapping. We even tried laying out units (which we traditionally have used the total station for), which may not be quite as accurate as a TS but the time-savings may very well offset it. What perhaps may be of most value, however, is their support. Since we were slightly anxious about taking into the field not only a newly purchased product, but a new-to-us set of instruments, I contacted their support and they immediately set up a WhatsApp support thread with us so that we could make inquiries and usually get responses within 24 hours. Their dedication to making their products easy to use in device design, UI design, and support structure is, perhaps, the real winner here. Can definitely recommend.

Excellent product, very pleased with what it offers, excellent precision; I recommend it 100%.

Product has a small learning curve. After that it is an absolute cost effect alternative for any company in the survey field. Fast shots and if you set up properly approximately 1/3 -1/4 inch accuracy. Customer service and support is great. We are going to field test it with our drone fleet next.

Is very straightforward to use and customer support is available

This is a amazing, sophisticated piece of equipment. i purchased to find my property stakes spread all over 50 acres of trees. Like a needle in a haystack. They have the best support i ever come across. I knew nothing of how to work this equipment but i feel their support turned me into a professional. I found all my stakes and saved over 100,000$ Our local land survey charge 5,000$ an acre on open land more with trees. I highly recommend this to anyone, well worth the money, Thank you SMAJAYU

I have been using custom base rover setups for a while and recently our company expanded and it has become nessasary to look into a plug and play setup. the sma26 is a very accurate stable and easy to use product which has given us the sub-centimeter data we need. i did have to send the sma26 back simply because it uses a newer radio frequency. We have many grade control systems that utilize trimtalk for rtcm corrections. I would like to point out that the v1 that has trimtalk works seemlessly with the existing trimble machines and hase saved us thousands a year as the smajayu devices allow full constellations without have to pay a service fee

Practically NO instructions. Had to return because this was too difficult to figure out. Their customer service was responsive and tried hard to help but Chinese product with terrible instructions. Don’t waste your time. Tried to find YouTube videos for help - very little available and those out there are bad.

Great instruments. I wanted to change from the conventional known brands without losing the level of accuracy and reliability I have always had. I found SMAJAYO GPS and I tested it against others. Excellent tool. I was able to easily match everything while using a fairly simple software that came pre installed in the android data colector. I am thinking about getting 2 more sets. I recommend.

MUY BUEN PRODUCTO YA LLEVO MAS DE DOS MESE CON EL, EL GNSS R26 - V2 ES MUY BUEN PRODUCTO YA QUE TIENE CALIBRACION DE LA NOAA PARA PROCESOS PPP ARROJA MUY BUENOS RESULTADOS AUN EN CIUDAD Y A CIELO ABIERTO MUCHO MEJORES POR EL METODO ESTATICO. EN RTK LA UNIDAD DE MODULO INERCIAL ES DE GRAN AYUDA YA QUE HAY PUNTOS DIFICILES Y TE AYUDA MUY BIEN. EN RESUMEN UN EQUIPO QUE VALE MUCHO LA PENA ADQUIRIRLO.

Muy buen equipo GNSS, cuenta con muy buena precisión, compactos, graban rinex, son completos y lo que me gustó más fue su colectora, la medición de inclinación y su forma de replantear con camara con la colectora.

Excelente equipo de topografía, el software me encanta mucho. Lo mejor que he usado en GPS

Levantamientos exactos y rápidos 👍

EXCELENTE PRODUCTO PARA TRABAJAR DE INMEDIATO. LAS ATENCIONES PARA DUDAS DE OPERACION SON EXCELENTES.
