abstract = {O emprego de receptores GPS na determina\c{c}\~{a}o de tempo, atitude e posi\c{c}\~{a}o tem se ampliado dada sua utilidade. Este trabalho descreve o desenvolvimento de receptores GPS baseado no conceito Commercial off-the-shelf (COTS), onde o cumprimento dos requisitos para uma aplica\c{c}\~{a}o embarcada em plataforma a\'{e}rea ou espacial pode ser atingido com a sele\c{c}\~{a}o adequada dos componentes e linhas de projeto adotados. O emprego de Sistema Operacional de Tempo Real (RTOS) com o conceito de plataforma General Public License-GPS (GPL-GPS), permite incorporar os algoritmos necess\'{a}rios \`{a} otimiza\c{c}\~{a}o das fun\c{c}\~{o}es de forma personalizada aos requisitos da miss\~{a}o da plataforma a\'{e}rea ou espacial.},

abstract = {Nowadays, the availability of microcontrollers from 8 to 16 bits and 32-bit microprocessors capable of executing 100 million instructions per second, allows the existence of applications that require the use of Real-Time Operating Systems (RTOS) in their embedded systems. This paper presents ameasurement environment to test an RTOS, in order to validate its use in special applications, such as satellite onboard software’s, once it must respondto critical constraints, like timing. In this case, the objective is to measure the latency time, through a high- performance FPGA,of an embedded system running the RTOS Real-Time Executive for Multiprocessor System spatial (RTEMS), widely used by community, for on board computer systems. Keywords RTOS , RTEMS , Embedded Systems, On Board Computer.},
