What arastelle does

Arastelle SAS is a French private company headquartered at Ester Technopole in Limoges, founded in 2019, that designs and sells tethered drone power systems for micro-unmanned aerial systems (UAS). Its core product, the BASTION ISR, is an ultra-compact (12 kg) tethered ground station that delivers continuous electrical power through an integrated cable, converting battery-limited micro-drones into persistent aerial platforms with effectively unlimited flight endurance, 100 m (330 ft) operational altitude, and a 30-second deployment envelope. Integrated batteries and plug-in or swappable power options allow field deployment in infrastructure-light environments. The system is engineered to interoperate without modification with four partner drone families: Harmattan AI's Sonora, Parrot's ANAFI UKR and ANAFI USA, and Red Cat's Black Widow and Teal 2.

Arastelle's commercial model is hardware-centric: it sells BASTION ISR units and related tether integration services to enterprise customers through direct field sales and OEM co-marketing with its drone manufacturer partners. Pricing is quote-based with multi-year contract cadence; no public list price is disclosed. The company addresses three primary verticals — defense and military (force protection, border security), public safety (event security, first responders, crisis management), and private sector security (critical infrastructure protection) — and claims adoption by militaries and first responders worldwide, though no named end customers or contract values are disclosed. The firm operates with 1–10 employees, has no registered patents, trademarks, or external funding rounds in the data set, and reports a fixed share capital of €81,970. Leadership comprises Adrien Danière as Président de SAS.

Operationally, Arastelle's strategic posture is platform-agnostic interoperability: rather than building its own airframe, it positions BASTION ISR as a complementary accessory layer across an ecosystem of leading micro-UAS vendors, leveraging partner go-to-market motions to access defense and security procurement channels globally.

Partnerships

Three partnerships are on record, tiered core.

• Sonora (Harmattan AI)coreTechnology or IntegrationARASTELLE offers tethering capability to the Sonora drone for enhanced ISR capabilities with no autonomy limits. Sonora is a quadcopter drone with a central camera system, and ARASTELLE's BASTION ISR enables unlimited flight time for this platform.
• Parrot (ANAFI UKR, ANAFI USA)coreTechnology or IntegrationARASTELLE technology is compatible with both ANAFI UKR and ANAFI USA drones, offering seamless and immediate tether integration for mission success. Parrot's professional drones gain unlimited flight autonomy when paired with ARASTELLE's tethered station.
• Red Cat (Black Widow, Teal 2)coreTechnology or IntegrationBlack Widow and Teal 2 drones benefit from ARASTELLE's tethering technology to expand mission capabilities with no flight time restrictions. Red Cat's platforms become permanent aerial watchtowers when integrated with BASTION ISR.

Emerging players

• DroneShield: DroneShield specializes in counter-UAS detection and mitigation. It does not sell tethered stations but competes for the same defense/security aerial-security budgets and serves overlapping procurement channels.
• Harmattan AI: Harmattan AI produces the Sonora quadcopter, an integrated partner platform for Arastelle's BASTION ISR. It is an emerging European defense drone OEM with overlapping ISR and tethered-mission use cases.

Direct peers

• Hoverfly Technologies: Hoverfly makes tethered and persistent drone platforms (e.g., BigQuad) for defense, security, and commercial applications. It directly overlaps Arastelle's tethered-power, persistent-ISR value proposition.
• Fotokite: Fotokite builds tethered drone systems for first responders, public safety, and news organizations. It is the closest direct competitor to Arastelle's BASTION ISR, offering continuous-power tethered flight for situational awareness with comparable target customers.
• Easy Aerial: Easy Aerial offers tethered and autonomous drone solutions for security, defense, and public safety, including the T-Cell tethered platform. It competes head-to-head with Arastelle in the persistent aerial surveillance niche.
