(SAR) beacons. The user might use the smartDF either to simply follow a Line of Bearing (LOB) / Line of Position (LOP), collect several LOBs to auto automatically create search zones, or to decode a possible target position from a COSPAS-SARSAT transmission.
Application 2.2.1 Licensing smartDF is a subscription-based application and requires a license key to use the software. A 7-digit license key will be provided to the user by RHOTHETA International. Without a license from RHI, the app will run in trial mode for 90 days, with Pro mode enabled. 30 days before expiration, the app will invite the user to reactivate the license.
Application 3 SmartDF UI Interface 3.1 Dashboard The dashboard provides a seamless view of essential parameters, such as bearing data, signal strength, and geolocation information. Its serves as the central hub for the operator and provides an immediate snapshot of critical data, enabling operators to rapidly assess and respond to radio direction finding scenarios.
Application 3.1.1 DF Control Panel e DF Control Panel provides real-time insights into the currently active frequency and its corresponding bearing to the source. Within this panel, operators have the flexibility to adjust the DF mode to align with mission demands. Furthermore, this panel can be customized to showcase the iPad's heading information for enhanced situational awareness.
3.1.2 Annunciator Panel The annunciator panel ensures operators stay informed about crucial system interfaces including data connection status to Rhotheta equipment, GPS and compass status, and if the screen lock is active to prevent unwanted inputs. Elements of the Annunciator Panel...

3.2.3.3 App & AU information The App and AU Info page within smartDF provides users with essential insights into both the application and the connected Antenna Unit (AU). Operators can quickly access details needed for maintance and troubleshooting without the need to physically inspect the antenna unit.

BLE will connect automatically when detected Once connected to Wi-Fi network smartDF will connect with the set IP address and Port Adds a constant offset correction to the bearing indication.
Application 3.2.4 Mapping Functions Menu The Mapping Functions menu provides convenient options for saving maps for offline use and deleting any unnecessary ones.This ensures uninterrupted functionality even when an internet connection is unavailable. Position the map to desired area and press the map...
Application 3.2.6 Save/Delete LOB/LOP Menu The Save/Delete LOB/LOP menu allows operators to save or remove LOB/LOP information on the screen/map for future reference. When two or more LOBs/LOPs are saved and the intersection aera option is activated, a search area is automatically generated, providing valuable assistance in locating transmission sources with increased accuracy.
Application ELT signals and intermittently transmitted ELT signals. Pulsed signals trigger an automatic squelch that self-adjusts based on received signals, and users can switch to manual mode if necessary. In cases where the Antenna Unit autonomously validates signals, user interaction isn't possible, and the squelch follows internal rules aligned with the received signal type.
Application 4.3 Bearing Mode In Bearing mode, bearing direction is derived from signals received relative to the DF system. Once the active frequency and squelch level are configured, bearing operations commence. When a signal is received, its strength is shown numerically (0% to 99%) and graphically using a bar graph, with the squelch level indicated correspondingly.
Application 4.4 Scan Mode 4.4.1 Scan Mode To initiate a scan mode of any band, simply press the DF mode button located on the DF Control Panel. While in scan mode, the system continuously scans frequencies within a designated band until a signal is detected.
4.5.2 LoJack Decoding LE version RHOTHETA antennas possesses the capability to track LoJack beacons. LoJack beacons are a Stolen Vehicle Recovery System. RHOTHETA antennas can decode these beacons to accurately track and identify their unique IDs. When tracking the ID will be displayed along the bearing line.
Application 5 Error and Warning Messages smartDF tracks and reports any Errors and Warnings that may arise during its operation. These notifications are displayed through a blinking warning symbol , drawing the operator's attention to potential issues. List of Errors & Warnings...
