de sua opera{\c{c}}{\~a}o como solu{\c{c}}{\~a}o t{\'e}cnica
e comercial para muitas das necessidades de imageamento,
comunica{\c{c}}{\~a}o, monitoramento dentre outras, fez com que
praticamente todas as ag{\^e}ncias espaciais investissem ao longo
dos anos na cria{\c{c}}{\~a}o de v{\'a}rios modelos de
ve{\'{\i}}culos e de suas opera{\c{c}}{\~o}es. As empresas
privadas fizeram o mesmo, criando solu{\c{c}}{\~o}es a serem
fornecidas aos pa{\'{\i}}ses usu{\'a}rios na forma de contratos
de servi{\c{c}}os, por{\'e}m de uma forma mais barata, com
facilidades para manuten{\c{c}}{\~a}o com menores custos e de
forma menos cr{\'{\i}}tica, al{\'e}m da possibilidade de
altera{\c{c}}{\~a}o de zonas de servi{\c{c}}o em
condi{\c{c}}{\~o}es mais favor{\'a}veis comparativamente aos
sat{\'e}lites. Isto demanda inclusive os controles de
posi{\c{c}}{\~a}o, orienta{\c{c}}{\~a}o, forma{\c{c}}{\~a}o,
colis{\~a}o, multiobjetivo, etc. dos ve{\'{\i}}culos. Assim,
nesse trabalho faz-se o estudo de uma estrat{\'e}gia de controle
para um HAPS. Isto inclui: 1) um levantamento bibliogr{\'a}fico
que aponta poss{\'{\i}}veis solu{\c{c}}{\~o}es para o
cen{\'a}rio de opera{\c{c}}{\~a}o de multi-HAPS; 2) o
cen{\'a}rio onde est{\'a} inserida a solu{\c{c}}{\~a}o dos
HAPS; 3) suas poss{\'{\i}}veis arquiteturas, componentes
principais, e 4) as dificuldades enfrentadas at{\'e} o momento em
alguns dos casos verificados. Isto permite concluir que: 1) a
formula{\c{c}}{\~a}o desses modelos passa pela escolha da
arquitetura e dos sistemas que ir{\~a}o compor sua estrutura e
possibilitar o longo tempo de dura{\c{c}}{\~a}o proposto para as
miss{\~o}es; 2) as limita{\c{c}}{\~o}es para sua longa
dura{\c{c}}{\~a}o na estratosfera demonstram caminharem para uma
solu{\c{c}}{\~a}o em breve; 3) a opera{\c{c}}{\~a}o dessas
plataformas em larga escala come{\c{c}}a a se tornar realidade e
desenhar cen{\'a}rios de um enxame de HAPS cobrindo
territ{\'o}rios inteiros; 4) o controle sugerido {\'e} promissor
para tal solu{\c{c}}{\~a}o. ABSTRACT: For some decades now, the
High-Altitude Platform Stations (HAPS) have been increasingly
relevant in the development of services previously offered and
covered only by satellites. The vision of this type of vehicle and
its operation as a technical and commercial solution for many of
the needs of imaging, communication, monitoring, among others, has
made virtually all space agencies invest over the years in the
creation of various models of vehicles and its operations. Private
companies did the same, creating solutions to be provided to user
countries in the form of service contracts, but in a cheaper way,
with facilities for maintenance at lower costs and in a less
critical way, in addition to the possibility of changing the areas
of service under more favorable conditions compared to satellites.
This demands even controls of position, orientation, formation,
collision, multi-objective, etc. of vehicles. Thus, in this work,
the study of a control strategy for a HAPS is carried out. This
includes: 1) a bibliographic survey that points out possible
solutions for the multi-HAPS operation scenario; 2) the scenario
where the HAPS solution is inserted; 3) its possible
architectures, main components, and 4) the difficulties faced so
far in some of the verified cases. This allows us to conclude
that: 1) the formulation of these models involves the choice of
architecture and systems that will compose its structure and
enable the long duration proposed for the missions; 2) the
limitations to its long duration in the stratosphere show that
they are moving towards a solution soon; 3) the operation of these
platforms on a large scale begins to become a reality and design
scenarios of a swarm of HAPS covering entire territories; 4) the
suggested control is promising for such a solution.",
