Technical Lake Kivu Challenge (LKC) Questions (16)
Are there other significant radio transmitters in the area (radio/tv broadcast, telecom/internet link systems, radars etc.)?
The LKC management team is not aware of any major sources of interference. Please contact us during Phase 2 around any specific concerns.
The LKC Flying Competitions require redundancy. ADS-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 LKC 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.
Yes, electric VTOL is required for the LKC Flying Competitions. For the Find and Assess competition, alternative launching and landing mechanisms and steep belly landings may be accepted. More detailed requirements can be found in the competition section of the website.
What are the allowed positions to place C2 systems and antennas (outside of takeoff/landing sites)?
Please contact the LKC 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.
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 Bugarura be outside of RLOS and if no RLOS at Bugarura, 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 October 4 and also test it in a 20km BVLOS flight? Is it possible to implement and test some of those in January, for example?
This documentation will be requested as part of Phase 2, which opens October 30th, 2019 and ends November 20th, 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 LKC 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 LKC team for consideration. For example, a proposal for utilising a relay drone as a VLOS operation at the droneport on the Rwandan mainland, restricted to below 400 ft AGL with an appropriate safety assessment of ground risk in the operations area
