Technology Related Competition Questions (16)
Are there other significant radio transmitters in the area (radio/tv broadcast, telecom/internet link systems, radars etc.)?
The LVC management team is not aware of any major sources of interference. Please contact us during Phase 2 around any specific concerns.
The LVC Flying Competitions require redundancy. ADS-B B (1090) is the preferred option, plus connecting the GCS to the UTM infrastructure for tracking. FLARM or Mode S SSR may be able to be tracked through the UTM system and the LVC team will provide updates when available.
For C2 link redundancy, can we implement for example a RF modem 868MHz 1W for telemetry and control as the primary link? And a 433MHz 500mW ? (With antenna tracking system)
We are in the process of clarifying permissible frequencies. Contestants should keep in mind RLOS when choosing their C2 telemetry.
For the C2 and Data-Link, which frequencies are available (preferable frequency ranges which are “common”, e.g. 868MHz, 900MHz, 2.3GHz, 2.4GHZ, 5.XGHz etc.)?
We are in the process of clarifying permissible frequencies; in general international standards are applicable.
For the Find and Assess Flying Competition, can a hand launched plane performing a belly landing or is a VTOL platform required?
A VTOL craft will be required for the Find And Assess Flying Competition.
GSM coverage is reasonable at the flying locations however we do not recommend reliance on it as primary C2 telemetry solution.
What are the allowed positions to place C2 systems and antennas (outside of takeoff/landing sites)?
Please contact the LVC team with a proposal for additional infrastructure during Phase 2 of qualifying.
What is the plan for co-ordination of frequency use by competitors while in the air and on the ground (frequency or time separation? Systems which allow multiple users)?
A deconfliction procedure will be shared with finalists. Expect tracking via a UTM system.
Link loss will incur significant minus points during the judging process. In the case where all links are lost, the craft should continue its mission based on autopilot settings.
We are in the process of clarifying maximum power.
We are in the process of clarifying permissible bandwidths.
Will the landing site on Juma be outside of RLOS and if no RLOS at Juma, is additional radio equipment allowed or provided there?
Contestants need to be prepared for landings outside of RLOS and may install additional equipment.
Will we need to test redundant C2 links onboard of our current commercial platform and send videos of it before April 29 and also test it in a 20km BVLOS flight? Is it possible to implement and test some of those in May, for example?
This documentation will be requested as part of Phase 2, which opens May 1, 2019 and ends July 15, 2019.
Would a drone with excellent performance in a few criteria generally fare more favourably than one with adequate performance all round?
We cannot comment on this to ensure the LVC Flying Competitions remain fair and competitive. All drones that take part in each competition need to be capable of fulfill the required use case. Scoring criteria will be released well ahead of the competition.
Not unless a favourable business (use) case and safety case to support this option were submitted to the LVC team for consideration. For example, a proposal for utilising a relay drone as a VLOS operation at the Mwanza droneport, restricted to below 400 ft AGL with an appropriate safety assessment of ground risk in the operations area
