The uBlox 6T is a popular L1 only chip set used by many for short baseline RTK work.\u00a0 Prices for these devices range from just over ~125 US dollars to about ~350 in single quantities depending on the model selected.<\/p>\n

uBlox Evaluation Model<\/a><\/h4>\n

Many people solve their L1-only GNSS needs with a uBlox 6T evaluation unit, shown below.\u00a0\u00a0 [Or, using the newer M8T which is gaining favor].\u00a0 Both can be obtained from directly the maker at the link above.<\/p>\n

You will likely connect it to uCenter (the firm’s evaluation software) with the the USB cable, and to another tool (such as RTKLIB) using a serial to USB cable.\u00a0 Incidentally, SNIP<\/strong> <\/span>can connect, obtain raw data, and control the device from either port.<\/p>\n

Remove the board from the aluminum extrusion, and this is what is inside the classic uBlox6T evaluation model. The USB port is at bottom left while a DB9 on the right side is connected to the 1st UART. The RF chain on this design has a handy filter that the other model below does not have.\u00a0 [Keep in mind that this product is intended as a reference design.\u00a0 The technical staff at uBlox will be of value to you if you intend to lay out your own design, as RF for L-band can be\u00a0 tricky.]<\/p>\n

CSG Shop<\/a><\/h4>\n

These boards from CSG are sold without enclosures, and look like this.
\nThe USB port is built in (upper left); the UART\/TTY is accessed from the pins on the left.<\/p>\n

<\/a><\/p>\n

OneTalent GNSS<\/a><\/h4>\n

Similar devices from OneTalent look like this.
\nThe USB port is built in (bottom edge); the UART\/TTY is accessed from the pins on the left.<\/p>\n

Hope this helps as a quick reference to the L1 only choices that are out there.<\/p>\n

Trying to do L1-only RTK on the cheap? – you are joining a large vibrant family.
\nVisit their sites, buy a unit – but also save some funds for a good antenna<\/a> if you expect to do RTK.<\/p>\n

Here is a short article<\/a> showing the level of performance you can expect to obtain with this device under good conditions.<\/p>\n
