![]() "VTT has led the way in the millimetre-wave satellite hardware development and in terrestrial 5G telecommunications radios. The signal it broadcasts will be observed at the prime contractor JOANNEUM RESEARCH's measurement station in Graz, Austria. The satellite, named W-Cube, will feature an integrated dual-frequency beacon transmitter developed by VTT. "Being selected by ESA to take part in this innovative project reflects the importance of the nanosatellite technology recently developed in Finland," commented Reaktor Space Lab's CEO Tuomas Tikka. ![]() ![]() The satellite to be built for the project is based on Reaktor Space Lab's "Hello World" satellite platform, which will be launched on its first mission this summer. The transmission of the signal through the atmospheric layers must be substantiated before telecommunications satellites that utilize the new frequency band can be designed with the desired features. The satellite's mission is to send, for the first time in history, such a high-frequency signal from space to Earth. ![]() The Finnish-made satellite weighs less than 5 kg, and its launch into space is scheduled to take place during 2019. The test flight will be carried out using a cost-effective CubeSat satellite. ”Pengolahan Limbah Lab dengan Sistem Bertingkat”, Laporan Penelitian, Medan.Funded by the European Space Agency (ESA) as part of its ARTES programme, this activity will demonstrate the use of the 75-GHz frequency band for future telecommunications satellites.

The results can be used as an indicator as the representation that the wastewater treatment of Baristand Industry is running well and is still operationally feasibleĪnni. Ratio BOD:COD is obtained linear regression with R 2 85,3 % for inlet and 86% for outlet. Monitoring of COD parameters is obtained the higher removal to 166,3 ppm or 80,33% while for the of BOD parameters is obtained higher removal to 64.1 or about 80.22%. Removal of COD and BOD parameters is done in each sampling and obtained quite fluctuate for each stage of the process and at the end of the process obtained a significant removal in both parameters. The results of the monitoring showed the removal of pH values at each stage of the fluctuating process where it obtained the lower pH value (inlet) at the end of sedimentation process while at the end of filtration process (outlet) has obtained the normal pH. The sampling point is conducted at the end of the process than it is observed of pH, COD and BOD removal. Wastewater treatment is done by multi stage trough many stages covers settling, coagulation, aeration and filtration process. Research was conducted the treatment of laboratory wastewater with multistage system reactor.
