3-
The RTK Torch runs the global firmware called RTK Everywhere. You can find its source [here](https://github.com/sparkfun/SparkFun_RTK_Everywhere_Firmware). Please see the [Quick Start Guide for the RTK Torch](https://docs.sparkfun.com/SparkFun_RTK_Everywhere_Firmware/quickstart-torch/) for a summary of how to get it connected over Bluetooth.

The RTK Torch benefits from an internal IMU that can allow a user to take very accurate location readings even if the pole is not completely vertical.

The IM19 inertial module fuses MEMS sensor and GNSS RTK positioning data to deliver low-cost, high-precision attitude measurement, delivering corrected RTK position data adding as little as 1cm inaccuracy to the position of the *point* of the surveying pole.

* Very fast calibration
22-
* Reduces overall mapping inaccuracies and increases productivity by not requiring pole leveling in the field
23-
24-
In Rover mode with Tilt Compensation, once RTK Fix is achieved, tilt compensation can be enabled by tilting the unit back and forth on a surveyor's pole. Once the IMU is activated, the outputted NMEA sentences will be modified to output the location of the *tip* of the pole (not the location of the receiver). This allows taking measurements near trees, structure corners, even underwater topographies with accuracies of +1cm when the tilt is less than 30 degrees, and +2cm when the tilt is less than 60 degrees.

The RTK Torch from SparkFun Electronics uses the UM980 high precision RTK capable GNSS receiver from Unicore ([datasheet](../Datasheets/UM980_Datasheet.pdf)). The receiver is capable of achieving the following accuracies:
8+
9+
* Single Point Positioning:
10+
* Horizontal: 1.5m
11+
* Vertical: 2.5m
12+
* DGPS:

*L1/L2/L5 helical antenna*
22+
23+
The UM980 is capable of receiving the following GNSS frequencies:
24+
25+
* GPS: L1C/A, L1C, L2P(Y), L2C, L5
26+
* GLONASS: L1, L2
27+
* Galileo: E1, E5a, E5b, E6
28+
* Beidou: B1I, B2I, B3I, B1C, B2a, B2b
29+
* QZSS: L1, L2, L5
30+
* SBAS
31+
32+
The RTK Torch utilizes a specially tuned multi-frequency helical antenna making the overall device smaller and more lightweight than competing units.
