# Firmware Overview
2+
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.

*RTK Torch on a Prism Pole with Bipod*
6+
7+
The RTK Torch has a standard 5/8" 11-TPI threaded base and is compatible with most equipment including surveying poles and equipment.
8+
9+
Users can elect to connect to the RTK Torch from a phone, laptop, or tablet. Any device with Bluetooth is compatible. See [Connecting Bluetooth](https://docs.sparkfun.com/SparkFun_RTK_Everywhere_Firmware/connecting_bluetooth/) for more information.

## Tilt Compensation
12+
13+
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.
14+
15+
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.
16+
17+
IM19 Features
18+
19+
* Extremely fast initializations, within 1~2s (95%)
20+
* Accuracy 1 cm up to 30° tilt angle, 2 cm up to 60°
21+
* 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.
25+
26+
For more information, see the [Tilt Compensation](https://docs.sparkfun.com/SparkFun_RTK_Everywhere_Firmware/menu_tilt/) feature in the product manual.

While the user should never need to open the RTK Torch, above is an image of the top of the main PCB assembly. This shows the ESP32-WROOM-32UE-N16R2 module (16MB Flash, 2MB PSRAM), the [UM980 Tri-band High Precision GNSS receiver](https://www.sparkfun.com/products/23286), the IM91 IMU / Tilt Compensation sensor, the [STM32WLE5CCU6 MCU](https://www.st.com/en/microcontrollers-microprocessors/stm32wle5cc.html) with built-in LoRa, and 1W amplifier/front-end (centered at 900MHz).
