L'usage de drone tether<\/a> to provide situational awareness was once the sole privilege of leading military forces who possessed the budget and the doctrine to employ them effectively. Following in the footsteps of previous military technologies such as the internet and GPS, UAVs are now commercially available and more importantly at an affordable price.<\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/elistair.com\/wp-content\/uploads\/2025\/08\/Drone-tether-First-responders-rescue-OP.jpg.jpg” alt=”Drone tether for first responders” title_text=”Drone tether First responders – rescue OP.jpg” align=”center” _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][et_pb_text _builder_version=”4.21.0″ _module_preset=”default” text_text_color=”#1E1E1E” text_font_size=”18px” text_line_height=”1.8em” header_2_font=”GT America Extended Regular||||||||” header_2_text_color=”#000000″ header_2_font_size=”34px” header_2_line_height=”1.2em” header_3_font=”GT America Extended Medium||||||||” header_3_text_color=”#000000″ hover_enabled=”0″ header_2_font_size_tablet=”34px” header_2_font_size_phone=”26px” header_2_font_size_last_edited=”on|phone” inline_fonts=”GT America Extended Regular,GT America Extended Medium” global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″]<\/p>\n This advancement in the availability of technology has allowed Emergency Services to bridge the capability gap and acquire tactical military grade surveillance assets; greatly enhancing situational awareness and the ability to respond to threats. Since 2014, UAV use by Emergency Services has steadily increased as departments became aware of the capability but more importantly operating procedures were developed to allow these units to be deployed efficiently, safely and in conjunction with local legislation [1].<\/p>\n The affordability of commercial UAVs makes them an attractive asset for procurement by Emergency Services who can benefit from the range of high resolution, day\/night\/FLIR optics that are available. The challenge comes from the trade off between payload vs endurance which has always been a delicate balance when conducting any kind of flying. Thrust must overcome weight in order for any kind of rotor craft to take off. Because of this, UAV\u2019s, which are currently reliant on batteries for their power source, see a decrease in endurance with an increase in payload. A DJI M600 boasts 32 minutes of flight time without any payload, but when fitted with a Ronin MX Camera (6kg) this is dramatically reduced to 16 minutes of usable flight time [2].<\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/elistair.com\/wp-content\/uploads\/2018\/05\/endurance-times-tethered-drone2.jpg” alt=”Surveillance drone” title_text=”endurance times – tethered drone” align=”center” force_fullwidth=”on” _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_image][et_pb_text _builder_version=”4.21.0″ _module_preset=”default” text_text_color=”#1E1E1E” text_font_size=”18px” text_line_height=”1.8em” header_2_font=”GT America Extended Regular||||||||” header_2_text_color=”#000000″ header_2_font_size=”34px” header_2_line_height=”1.6em” header_3_font=”GT America Extended Medium||||||||” header_3_text_color=”#000000″ hover_enabled=”0″ header_2_font_size_tablet=”34px” header_2_font_size_phone=”26px” header_2_font_size_last_edited=”on|desktop” header_3_font_size_tablet=”” header_3_font_size_phone=”” header_3_font_size_last_edited=”on|phone” inline_fonts=”GT America Extended Medium” global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″]<\/p>\n For some applications a 20-30-minutes flight time is adequate, searching an area for a fugitive or missing person can be completed quickly and then the UAV can be recovered, batteries changed before moving on to the new area to be searched. Equally in these instances it is the UAVs freedom of lateral movement which provides its greatest value as it can quickly cover a lot of ground which may be inaccessible or even dangerous for responders to access. When Endurance is required there are two main options available: A supply of readily charged batteries or providing a continuous power source by tethering.<\/p>\n UAVs tethers trade lateral movement for increased endurance as they are physically and securely connected to a ground station by a micro-tether. This tether not only provides the physical security of keeping the UAV in place but also provides power and in some cases the ability to transfer secure data which, because it is not being transmitted by Radio Frequency, cannot be jammed. By tethering their UAV, Emergency Services gain a persistent Intelligence, Surveillance and Reconnaissance (ISR) asset which provides levels of situational awareness that were previously unobtainable.<\/p>\n Surveillance de la circulation<\/a>, crowd control and event security<\/a>\u00a0–\u00a0A tethered UAV with an XDM x30 zoom camera can detect a human at 10 km and can cover a 300 km2 <\/sup>area [3].<\/p>\n VIP\/Diplomatic protection \u2013<\/strong> Tethered drone systems provide an overt deterrent which can be rapidly deployed and redeployed in response to changing situations.

This buys time for infrastructure to be repaired and services bough back online and more importantly is more portable and rapid than erecting masts.<\/p>\n Drone tethers<\/a> need a power source to operate, mains power (if available), portable generators or emergency vehicles equipped with an invertor all provide options for successfully deploying a tethered UAV. The flexibility of a tethered UAV system that incorporates the original battery allows rapid re-rolling from tethered to un tethered flight as the situation evolves. Other tactics that can be utilised to increase flexibility include utilising a tethered UAV with a second traditional UAV. The tethered asset provides uninterrupted overwatch of the scene, if it spots an area of interest or if the situation becomes mobile the untethered asset is launched to investigate.<\/p>\n Compatibility<\/strong> \u2013 New drones are being developed and released at a staggering rate. A tethered system that is compatible with a wide range of the most capable systems is essential to future proof drone operations.<\/p>\n Survivability <\/strong>\u2013\u00a0The tether system needs to be able to operate in challenging weather conditions, it must be ruggedized to operate in different climates and in extremes of environments.<\/p>\n Technologically advanced \u2013\u00a0<\/strong>The tether must be as lightweight as possible but also have the ability to provide the necessary power and data transfer. The tether must be manufactured from lightweight but strong material and rated to a suitable breaking strength >100kg. Monitoring applications, remote control and automatic deployment all decrease workload and increase the capacity of the operator.<\/p>\n Different options to fit different applications \u2013<\/strong>\u00a0There is no one size fits all, a range of available options (weight, height, size, power) ensures that the correct asset is deployed to the correct job.<\/p>\n Find out more about our solutions here<\/a> [\/et_pb_text][et_pb_text _builder_version=”4.21.0″ _module_preset=”default” text_text_color=”#1E1E1E” text_font_size=”18px” text_line_height=”1.8em” header_2_font=”GT America Extended Regular||||||||” header_2_text_color=”#000000″ header_2_font_size=”34px” header_2_line_height=”1.2em” header_3_font=”GT America Extended Medium||||||||” header_3_text_color=”#000000″ hover_enabled=”0″ header_2_font_size_tablet=”34px” header_2_font_size_phone=”26px” header_2_font_size_last_edited=”on|phone” inline_fonts=”GT America Extended Regular” global_colors_info=”{}” theme_builder_area=”post_content” sticky_enabled=”0″]<\/p>\n REFERENCES<\/p>\n [1] Gettinger, D. “Public Safety Drones.” Center for the Study of the Drone.
