1 Multi-droe four-dimesioal flight costrait maagemet Abstract With the emergece of the umaed aerial vehicle (UAV) eco-system for commercial ad eterprise markets, multi-droe traf c maagemet has become critical to esure ef ciecy ad safety of 1 airspace. Guidelies pertaiig to umaed traf c maagemet (UTM) are beig drafted, ecompassig air traf c cotrol, detect, sese, ad avoid (DSAA) techology, 3D ight plaig, ad ight safety with geo-fecig ad o- y zoes. Itroductio of autoomous droes caterig to multiple market segmets across telecom, retail, maufacturig, trasportatio, healthcare, ad public safety madates a more robust traf c maagemet approach. While three-dimesioal airspace maagemet icludes ovel approaches such as sky-laes ad sky-corridors, additioal fourdimesioal (airspace ad time) ight costraits moitorig ad mitigatio is critical to eable collisio-free ad safe ights. This paper focuses o a autoomous approach to resolve 4D costraits. It takes ito cosideratio that the origial ight pla of the multi-droe ecosystem is ot chured durig 4D costraits resolutio. This is a importat value-add, as 3D co ict resolutio usually ivolves deviatio from the plaed ight path.

2 Treds ad Challeges The addressable market for a cosolidated droe ecosystem is 2 expected to grow to $127 Billio by This expoetial rise is beig drive by rapidly evolvig droe techologies that power ew busiess ad operatig models. Use cases employig droe techology spa multiple idustries, where droes are beig itegrated with existig busiess processes, eablig Droe-as-a-Service. As the ecosystem evolves ad droes are widely deployed, the eed for effective airspace maagemet also becomes importat. I the maed airspace, air traf c cotrol (ATC) maually caters to ad resolves the 4D costraits. However, i the UAV ecosystem with multiple droes, maual itervetio would be time-cosumig ad proe to humaerror, ad is ot a optimal solutio. A autoomous approach to moitor, detect, ad mitigate 4D co ict would be the preferred ad recommeded approach for streamlied UAV traf c maagemet. Advacemets i techology are already powerig autoomous ad beyod visual lie of sight droes (BVLOS) ights that would be leveraged for Droe-as-a-Service. Idividual UAV service suppliers (USSs) would coordiate with UTM providers for ight pla veri catio, approvals, ad real-time moitorig. While the ight plas get validated for airspace, ight path ad o- y zoe co icts, 4D costrait moitorig ad mitigatio will be essetial to ehace the safety ad service effectiveess of autoomous or BVLOS droes. Approach Let us cosider a use-case where idepedet UAV service suppliers are deliverig Droe-as-a-Service for retail-delivery at a eterprise. While the idividual ight plas are preapproved by UTM, airspace ad time costraits could be ecoutered. Imagie a sceario where two packages, oe cotaiig medical supplies ad the other with corporate letters from differet USSs, are arrivig at the same time at a compay s desigated ladig zoe. While each of the above services eeds to be executed, the co ict must be tackled to esure that the USSs are successful i deliverig the packages ad meetig their SLAs.

3 We preset a approach to moitor ad resolve these 4D costraits by employig a localized, multi-droe airspace 3 maager. The airspace maager is a setup of ArduCopter ad 4 MAVlik, represetig multiple USSs i the ecosystem, to which the groud cotrol is itegrated through ope REST APIs 5 usig ICAROUS. The approach takes ito cosideratio the existig recommedatios of UTM applicable for USSs, ad implemets a modular plugi, icorporatig applicatio logic ad iterface to USSs to maage the 4D costraits. Moitor, Detect, ad Mitigate The approach has bee desiged for a localized multi-droe eco-system, where multiple USSs are providig Droe-As-A- Service. I this use case, we have cosidered USS-1 deliverig critical medical supplies ad USS-2 deliverig stadard corporate letters at the eterprise s desigated ladig zoe.

The solutio registers ad starts moitorig the droes oce they eter the eterprise s outer perimeter, ad computes the possibility of a 4D co ict betwee the idepedet USS droes. If such a costrait is detected, the solutio works with the USS UTM system to take ito cosideratio additioal ight parameters- service prioritizatio, service type, payload type,

It the uses the pre-de ed busiess logic to recommed the mitigatio pla to the USS droes loiter withi the ier perimeter or proceed to y to the ladig zoe. The idepedet USSs are directed to execute the mitigatio pla, thus resolvig the 4D costrait. Post co ict resolutio, the droes proceed with the approved ight paths. The key teet of the approach is that the origial approved ight path of the USS droe is ot altered to maage the airspace ad time co ict.

While this paper demostrates the recommeded approach for 4D costrait maagemet, there is scope for additioal ehacemets to tackle more complex co icts. Some of these are: Fleet maagemet: Provide Droe-as-a-Service, leveragig a eet. Withi the eet, the respective USS would hadle costraits, ad across idepedet USSs, four-dimesioal costraits would be moitored ad resolved.
