UAV Automated Landing System (TALS) based on optical recognition. Here is model of data processing, simulates video from drone camera. Captured video is viewed to define featured points – markers in runway.
Detected marker is labeled by green rectangle, that will be one of the targets in the video frame. Group of targets defines runway and its spatial position qq663pn. Tracking system traces group of targets during landing and produce control signals for the autopilot.
TALS (Tracking Automated Landing System) is an automatic landing system addressed to UAV applications. It is based on two independent and cooperative sections whose combined processing allows to feed attitude and position parameters to UAV autopilot.
The first section is based on a AHRS platform integrated with a GNSS/SBAS corrected signal (GPS,GLONASS,GALILEO or any other available satellite positioning system implementing augmentation). It is able to provide the UAV position with accuracy better than 3m.
SIP / VoIP gateway is based on the carrier board with a digital bus, on which the bladed interface modules can be installed (see starting from the upper right corner). The photo shows 6 modules installed and two more free space for the left. Interface modules have connectors for external audio devices. In the lower left corner is shown embedded ARM / DSP computer module.
The gateway is designed to provide the functions of digital voice “Voice over IP” (VoIP) and switching media streams via SIP in the air traffic voice system controller – pilot, according to the requirements of the standard ED-136 and ED-137 A / B EUROCAE.
The main focus of the company is a Passive Coherent Location (PCL). Primaria developed a PCL prototype named “Prim Ceramic 2700”. Passive radar uses components with a high value of the intellectual property. This IP is based on research and development programs in the field of PCL and Direction Finders signal processing.
The key components of the passive radar “Prim Ceramic 2700” are:
More about Passive Radar “Prim Ceramic 2700” is described below.
Primaria team originates from the 1980s and develop Airport Direction Finders (DF) with a focus on software and hardware signal processing. Starting from 2013, the main project of the company is the development of a Coherent Passive Radar “Prim Ceramic 2700”.
The Direction Finders signal processing was implemented in the following products:
Prim Ceramic 2700 Signal Processing Unit contains a chain RF Module -> ADC – > FPGA -> DSP. In the terminology of PCL, the unit is a frequency channel, or a bistatic section. Prototype includes two bistatic sections, allow resolve targets due to crossing two ambiguity ellipses.
