good morning to every body,
i will first of all tell you that i'm a french speaker and i just try to speak and write english. so allow me to introduce some french word during my explanation.
so i manage a base station in cameroon and our provider is skyvision; our vsat is pointing on amc12. the problem is that our ping vary hour from hour. for example some day in the morning before 9oclock the ping from our dns offer by sky is 600 to 650 ms but after 9h it pass to 1000ms ,1200ms , and some time to 1500ms. and some time they are some request time out.but in the night the ping recovers 600to 650ms.
please what could be the problem? because when this appear it disturb our service and then the QOS IS BAD. Please is it some "appareil de mesure" to test our link with sky or with amc12?
i 'll tell you that we provide many services like internet, voip, vpn and so on to our customer.
what is the normal request time of ping from one base station on earth to one satellite.
please could some body help me?
thank you for your attention.
best regard.

hi, this is ROHIT , i am in Nairobi, Kenya. The normal round trip from your earth station to satellite and back is 500-600 ms.

dear meme,

u did nt mention the type of service you are utilising ,DVB or SCPC. what kind of indoor unit do u have? the ping you are running is it to DNS server or gateway ? is it satellite to Earth station?( satellite to earth station with good pointing shld give 500-600ms). u need to talk to your service provider, maybe they have a solution for you.

we have this problem once. BUC not normally working or antenna pointing. Check parameters when ping growing up.
