Bring Accuracy and Flexibility On-Site with SATEL’s Compact-Proof
Laser Specialists Inc, a long-time, valued dealer of Satel USA, has been using the SATEL Compact-Proof together with SenseFly’s eBee mapping drone for added RTK accuracy and flexibility on-site. This easy set up has been ideal for Laser Specialists’ mining and construction clients, finding use in quarries, stock piles, excavation and highway construction, where accurate maps and 3D models are needed to calculate volumes and perform site surveys.
The added flexibility the SATEL Compact-Proof provides is an operational advantage. Versus being physically tied to the RTK base at a specific location, the SATEL radio link allows the drone operator to place the base anywhere onsite and move around as needed throughout operation. With the Compact-Proof’s built-in battery and IP67 housing, the radio is conveniently mobile and can easily operate for a full day on-site, holding up to the dust and rugged elements of a construction site.
The improved accuracy is also significant. In standalone operation, the drone flies within 10-15 ft accuracy. With the RTK base and SATEL Compact-Proof in place, that accuracy ranges from .9 to 1.5 cm, a drastic improvement that is especially valuable across construction and earthwork movement applications. As Eric Wischropp of Laser Specialists explains, this accuracy is appreciated even in the operational task of landing the drone. With RTK accuracy, the drone can easily be brought down in most locations on the job site. Without this accuracy, the operator has a more difficult and tedious task, needing to strategically identify a larger area for safe landing.
The Compact-Proof connects via USB data cable to the drone operator’s laptop, which runs the eMotion software that routes the UAV through its predetermined route. The Compact-Proof provides a real time data link to the base, which sends position corrections to the GPS receiver on the eBee every second, with an audible indication as images are captured. The built-in battery on the Compact-Proof makes for an easy, mobile solution, allowing the operator to move across the job-site as needed.
The SATEL Compact-Proof can also be used as an external radio at the base, if the GPS unit is without a built-in radio. At 1W output power, the Compact-Proof can easily cover the range needed for most drone flights. The UHF signal also outperforms 900 MHz ISM and makes for much more reliable connectivity. In other cases, such as a long-range roadway project, Laser Specialists has integrated the SATELLINE-EASy Pro 35W, either at the base or as a repeater, to allow for a larger working range. This solution provides the possibility of integrated machine positioning and robust onsite capabilities.
Satel USA provides a complete Compact-Proof kit for easy set up. For more information and pricing, please contact Laser Specialists Inc. (Ph. 913-780-9990, email@example.com), or your local Satel USA dealer.
The most frequent cause of Satel Radio issues is a mismatch in settings between the transmitting radio and the receiving radio. The key settings that must be the same on both radios are:
Note: On other Satel-compatible radios, or via 3rd party interfaces (such as Leica or Carlson Software), these terms may have different names. Other settings, such as Error Checking are uncommonly used.
The above steps cover the most common issues seen when setting up a Satel radio system. If the instructions don’t address your situation, or you are unsure how to match settings on a Satel-compatible device, such as a radio from another manufacturer, or via 3rd party configuration software, please contact us.

SATEL’s latest high power, heavy-duty radio modem, the SATELLINE-4Pro includes the reliable features you’ve come to trust in a SATEL 35W transceiver, while also offering faster data speed (14400 bps at 12.5 kHz) at 8FSK and 16FSK modulations. The radio also allows for adjustable output power, to as low as 2W. This is a most appreciated feature for applications such as Machine Control, allowing operators to save crucial battery life on-site. IP67 classified housing ensures protection against moisture and dust. 406.180—470 MHz tuning range and selectable bandwidth of 12.5 or 25 kHz. Available in Survey Mode only. The LCD and keypad can be used to monitor the current operating status, as well as to change the operating channel and power level of the radio. The SATELLINE-4Pro is compatible with all SATELLINE-EASy products (8FSK and 16FSK modes are only compatible with 4Pro and TR4 based models). Wondering which radio better fits your needs, the classic EASy Pro 35W or the SATELLINE-4Pro? See comparison below:

SATEL Configuration Manager is an essential tool for loading settings to your SATEL modems. One feature that can make that fast and easy is the ability to load settings from a pre-existing file. That way, if you need to load the same settings and/or a channel list on multiple units, you don’t need to individually key in the settings for each one. The settings of the first unit you set up can be saved to your PC by clicking on “Save Configuration to File”. On the next radio you set up, click “Load Configuration from File” and “Open” the cfg file that was saved. When completed, all loaded settings are red and an info tablet opens stating “Configuration file loaded successfully!”. The settings are then uploaded to the radio by clicking “Write Settings” on the top tab of Configuration Manager. Settings files should only be used across matching models, so settings for the EASy 1W should not be loaded to the EASy Pro 35W, for example.
When in Survey Mode, there is a helpful feature specifically for channel lists. You can save the channel list separately and in a format that can be used across SATEL radio models, as long as the “Tx Power” setting is set to “0”, indicating that the maximum power can be used. Select the “Program Preferences” tab, enter password for maintenance mode, then in “Modem Settings” select “Open Channel Selector”. Build your channel list by selecting “Add” and remember to put “0” in “Tx Power” (unless you have restrictions that prohibit you from doing so). Select “Save” to save the channel list to your computer to load to other radios. Select “Load” to load to your current radio, then click “Write Settings”.
Note that the Satelline-4Pro requires Configuration Manager version 1.6.1—that and the Configuration Manager User Guide can be found on our website, under Service>Software.
Error Correction is an available setting in all SATEL radio modems, which can help improve data transfer in cases of poor or unreliable communication. Referred to as FEC Mode (Forward Error Correction) in Configuration Manager, note that this setting refers to SATEL 3AS Error Correction and does not affect other compatibility modes, such as PacCrest. This setting can be turned ON or OFF both in Configuration Manager and directly on the front screen of your radio modem.
When Error Correction is enabled (ON), the radio modem automatically adds additional error correction information, which increases the amount of transmitted data by 30%. It is used by the receiving radio modem to correct erroneous bits, as long as the ratio of correct and erroneous bits is reasonable. The resulting benefit can be an improvement of up to 3dB sensitivity.
Error Correction improves the reliability of data transfer via the radio interface, especially in unfavorable conditions. The Error Correction function should be used when link distances are long or received signal is otherwise low due to poor propagation conditions or multi-path fading. It is also recommended to use Error Correction in case there are intermittent interferences on the radio channel.
The Error Correction function decreases data transfer throughput by approximately 30%. Though transfer delays are longer, Error Correction can be quite useful for the best data transmission quality in the scenarios described above.
Few radio parameters can be as confusing as modulation and over-the-air speed, not only for the novice user, but also for the experienced. Here are a few comments that hopefully help to shine some light on the subject:
Although Port Speed and over-the-air speed have some relation to each other, they are totally separate settings.
While the Radio Port speed and GPS receiver Port speed must match exactly (for example GPS = 9600 bps & Radio = 9600bps), to allow the normal transfer of data over the connecting cable, the speed over-the-air cannot be set by simply changing the Port speed. It’s actually a fixed value which depends on both bandwidth and modulation.
In the US, the most common bandwidth today is 12.5kHz. So if your radio uses any of the following modulations:
– SATEL 4FSK, PacCrest 4FSK, PacCrest FST at 12.5kHz,
the speed over the air is fixed at 9600bps.
Whereas if you are using the following modulations:
– PacCrest GMSK, or Trimtalk 450S at 12.5 kHz, the speed over the air is fixed at 4800bps.
If a half-speed modulation type such as GMSK is used, the Base radio Transmitter is on-the-air for twice the length of time respect to a faster modulation. This means higher battery consumption and more overheating of the radio itself.
Modulation can be an even more complex subject and it has a major influence on both the speed over the air and the actual range of the radio equipment.
The most common modulation today is 4FSK (4 Frequency Shift Keys). This means that the radio transmitter (base) transforms the NMEA data from the GPS into radio frequency variations that shift to 4 different points around its central working frequency. All the points must be contained within the 12.5kHz required by the FCC. This means that the TX will constantly “shift” to 4 frequency points, up to 6.25 kHz away from its central frequency, both to the right and to the left in the frequency spectrum. A rough example: the Tx “shifts” from its central 450.000000 MHz to -> 450.006250 MHz and then back and forth from and to -> 449.9993750 MHz. Each “shift” is interpreted as a data 1 or zero and the whole NMEA string of the GPS is recomposed in the rover.
Some equipment offer even higher over-the-air speed by using more complex types of modulation (ex. 8FSK, 16FSK). Some even use 32QAM, where not only frequency “shifts” but also “phase” variations are measured. SATEL offers an internal OEM module, already in production and used by major GPS manufacturers, with 8FSK and 16FSK modulation and over-the-air speed up to 14400bps. This becomes useful when several constellations are received (for example GPS + GLONASS), which cause the radio to transmit more data. In order to be able to contain all data within 1 Hz (once a second) a higher over-the-air speed is desirable. The downside of higher modulation is that the receiver must work harder to detect very small variations, thus a stronger radio signal is required to counterbalance the environmental noise present in the air. Ultimately this means a decreased working range.
